An Older Sister's Guide to Not Screwing Up Your Finances (From Someone Who Did)

I have a younger sister. She's Gen Z, she's never wanted for anything, and she has genuinely never had to think about money the way I have — because my dad and stepmom were in a much better financial position by the time she came around. Meanwhile, I grew up with divorced parents — a mom working minimum wage, raising three daughters, and a young dad raising two daughters, wildly unprepared. Same family. Completely different financial starting lines.

I'm not telling you that to be bitter about it — I made my peace with that a long time ago. I'm telling you because I want you to understand where this advice is coming from. Not from someone who was handed a playbook. From someone who figured it out the hard way, made a lot of expensive mistakes, and genuinely wishes someone had sat her down at 22 and said: here's what actually matters.

So consider this that conversation.

Let's Start With the Avocado Toast Thing, Because I'm Tired of It

You have probably been told, at some point, that if you just stopped buying iced coffees and avocado toast you could afford a house. I need you to know that this is one of the most condescending pieces of financial advice ever dispensed, and the math does not remotely support it.

As of March 2026, the median home price in the United States is $436,523. The average sale price sits even higher, at $514,600. And if you live anywhere near a major city — New York, Los Angeles, Boston, DC — you can add another zero to your anxiety. New York's typical home value sits around $708,000; Los Angeles is closer to $946,000. Redfin + 2

A $7 iced coffee, five days a week, fifty weeks a year, is $1,750. That is not a down payment. That is not even a rounding error on a down payment. Cutting your latte will not save you from a housing market that has increased 22.6% since 2020 while wages have not kept pace. So please, enjoy your coffee. The problem is structural, not caffeinated.

What will actually move the needle is starting earlier than feels necessary with the tools that are actually available to you. Which brings me to the thing I wish someone had screamed at me at 22.

The Roth IRA Conversation Nobody Had With Me

I did not open a Roth IRA in my 20s. I did not even fully understand what one was until embarrassingly late. And it is genuinely one of my biggest financial regrets — not because I needed to contribute thousands, but because of how compound interest works and how badly time matters when it's working for you.

Here's the simple version: compound interest means you earn interest on your interest. Your money grows on top of itself. The longer it has to do that, the more dramatic the result — and the difference between starting at 22 versus starting at 32 is not ten years of contributions. It's potentially hundreds of thousands of dollars.

Let me make this real. If you put $50 a month into a Roth IRA starting at age 22, with an average annual return of 7% (a conservative estimate based on historical stock market averages), by the time you're 65 you'd have roughly $175,000 — on $25,800 of actual contributions. If you wait until 32 to start that same $50 a month? You'd have around $85,000. Same contribution amount. Ten fewer years. Ninety thousand dollars less. That's what compound interest does, and that's why starting early — even small — matters so much more than waiting until you can "afford to do it properly."

A Roth IRA specifically is worth understanding because contributions are made with after-tax dollars, which means all future growth is tax-free. You pay taxes now, on money you've already earned, and then you never pay taxes on it again — including all the growth. The contribution limit for 2026 is $7,500 for those under 50, which works out to about $625 a month if you want to max it out. But you do not have to max it out. You just have to start.

Pro tip: If your employer offers a 401k match, take the full match before you do anything else. That's free money. I max out my employer match and I'm genuinely proud of that — it took me years to get there. Then, if you have anything left, open a Roth IRA. Even $50 a month. Even $25. Start the account. Let time do the rest.

Social Security Probably Won't Save You. I'm Sorry.

This is the part where I have to tell you something uncomfortable.

You are paying into Social Security right now. Every paycheck, money comes out. And the honest reality is that by the time you retire, the program as it currently exists may not be able to pay you what it's promising. The 2025 Social Security Trustees Report projects that the primary trust fund will be depleted by 2033. Unless Congress acts, beneficiaries would see an automatic cut of around 23%. Bipartisan Policy Center

In 1960, there were 5.1 workers paying into Social Security for every retiree collecting benefits. Today, that ratio is 2.8 — and it's projected to drop below 2.5 by mid-century. Fewer workers, more retirees, longer lifespans. The math is not working in your favor. The College Investor

This doesn't mean Social Security will disappear entirely — Congress will almost certainly do something, because they always do something when the alternative is political suicide. But millennials and Gen Z may face higher taxes and reduced benefits despite paying into the system their entire working lives. Plan accordingly. Do not build your retirement around a check that may be 23% smaller than promised, or may arrive later than expected, or both. The College Investor

Build your own safety net. Roth IRA. 401k. Index funds. Something that is yours, that doesn't depend on Congress getting its act together by 2033.

The Doomspending Problem (This One's Personal)

I am a neurodivergent ADHDer with what I will generously describe as an impulsive relationship with my own dopamine. And for years, before I understood any of that about myself, I was a marketer's dream.

I'm talking about lying in bed at 2am, deep in an Instagram spiral, absolutely convinced that I needed a specific brand of mushroom coffee or a weighted eye mask or a skincare tool I'd never heard of four minutes ago. I bought things I didn't need, wouldn't use, and couldn't really afford. Not because I was stupid. Because my brain was chasing a hit.

When we add things to our cart or respond to a notification, our brains release dopamine — the feel-good chemical that motivates us to do it again. In people with ADHD, this response is amplified because the brain is already running low on dopamine and actively seeking ways to get more. Impulse spending provides immediate gratification and a feeling of reward that's difficult to resist — and social media apps have made purchases for everything imaginable just one click away. The algorithm knows exactly what you want before you do. I was not weak. I was targeted. MediumMillennial Therapy

ADHD symptoms correlate directly with credit card balances carried, late payments, and financial distress in adulthood. There's even a term for it: the ADHD tax — the ongoing financial cost of impulsivity, disorganization, and poor financial follow-through that compounds over time. Cash Essentials

Getting diagnosed — late, in my case — helped me understand the pattern. But understanding it wasn't enough on its own. I had to build actual systems.

The Tools That Actually Help

I'm not going to tell you to "make a budget" and leave it there. That advice is useless without context. Here's what I actually use:

RocketMoney for tracking spending and subscriptions. It connects to your accounts, categorizes everything, and will very gently show you how much you spent at Target last month in a way that is both informative and spiritually painful. It also finds subscriptions you forgot you had. I have cancelled things I had been paying for for literally two years without knowing.

My own spreadsheets for debt payoff tracking. I built them myself, and I track every payment, every balance, and every projected payoff date. There is something deeply satisfying about watching the numbers go down, and for my ADHD brain it creates the same kind of dopamine reward as moving a Kanban ticket to "Done." If spreadsheets are not your thing, that's fine — but find some visual way to track progress. Your brain needs to see the movement.

YNAB (You Need A Budget) is on my list to try. I haven't used it personally yet — I'll be honest about that — but it's consistently recommended for neurodivergent people specifically because it works on a zero-based budgeting system where every dollar is assigned a job before you spend it. That kind of structure is exactly what an ADHD brain needs, and the reviews from people like us are genuinely good.

A 24-hour rule for non-essential purchases. If I want something I didn't plan to buy, I put it in my cart and wait a day. Half the time I don't want it anymore (or forgot about it). The other half of the time I still want it and buy it, but at least it was a choice instead of a reflex. This single habit has saved me more money than any budgeting app.

Spend Money On What Actually Matters To You

Here's where I'm going to say something that might surprise you coming from a finance post: not all spending is bad spending. In fact, the "save everything, sacrifice everything" approach to personal finance is just as misguided as doomspending on Instagram at 2am.

I went back to school for my MBA at 38. I still have student loans — both from undergrad and now from grad school — and I will probably be paying them off until I'm 60. By conventional financial wisdom, that is a terrible decision. By my own value system, it's one of the best investments I've made in myself.

Spend money on what matters to you. Travel, if that fills your cup. Investing in a skill or a side hustle. Collecting things that bring you genuine joy. Flipping properties if you have the stomach for it. You don't need a college degree if college isn't your path — trades are an incredibly viable route that financial advice spaces chronically undervalue. The goal isn't to follow someone else's blueprint for how money should be spent. The goal is to be intentional about it — to choose, rather than drift.

The distinction is simple: does it add value to your life, or does it fill a hole temporarily? One is spending with purpose. The other is the 2am Amazon spiral. Learn to tell the difference, and then spend accordingly.

The Short Version, If You Need It

Start a Roth IRA. Now. With whatever you have. Take your employer's 401k match if you have one — every penny of it. Do not count on Social Security to carry you. Build a system that shows you where your money is going, because you cannot fix what you cannot see. And stop letting Instagram sell you things at midnight.

You're not bad with money. You just weren't taught any of this. Neither was I.

Now you know.
