7 hard truths about growing older that no one prepares you for

I’m in my mid-thirties now, which feels like this weird in-between stage of life. Not quite young anymore, but definitely not ‘old’ either. It’s a strange place to be, honestly.

When I was in my twenties, I thought I had it all figured out. I thought getting older meant climbing the ladder, making more money, and eventually just…settling into some comfortable routine.

But here’s the thing nobody tells you: growing older is nothing like what you expect.

Sure, there are the obvious changes – a few more aches after a workout, needing slightly more recovery time after a night out. But the real shifts? The ones that actually matter? Those caught me completely off guard.

Today, I want to share some truths about aging that I wish someone had told me earlier. Not to be depressing, but because understanding these things has actually helped me navigate this whole “getting older” thing with a bit more grace.

1. Your body starts giving you feedback (whether you want it or not)

Remember when you could eat pizza at midnight, sleep four hours, and still crush a workout the next day?

Yeah, those days are fading fast.

I used to survive on terrible food and minimal sleep. My body just…took it. No questions asked. But somewhere around my early thirties, things changed.

Now, if I skimp on sleep, I pay for it. If I eat junk for a few days straight, I feel it immediately. My body has become way more demanding about what it needs to function properly.

The hard truth? You can’t coast on the resilience of youth forever. Taking care of your health isn’t optional anymore – it’s essential if you want to feel good and keep doing the things you love.

2. Time moves differently 

Here’s something that messes with my head: time speeds up as you get older.

When I was a kid, summer vacation felt like it lasted forever. A year felt like an eternity. But now? I blink and it’s December. Again.

There’s actually science behind this.  As put by senior lecturer in psychology Leeds Beckett University, Steve Taylor, Ph.D., “Time speeds up with increasing age because we have fewer new experiences and our perception is less vivid.”

It makes sense, right? When every day looks basically the same, your brain doesn’t create as many distinct memories. The days just blur together.

This realization hit me hard when I was stuck in that corporate grind. Years were flying by, and I couldn’t really remember what I’d done with them.

The hard truth? If you don’t actively create new experiences and break up your routine, years will disappear before you know it. Time is going to move faster whether you like it or not, but you have some control over how memorable those years are.

3. Your priorities shift 

In my twenties, I cared deeply about impressing people. The right job title, the appearance of success, what others thought of my choices – it all mattered.

Now? I genuinely don’t give a damn about most of that stuff.

These days, I care more about whether I’m doing work that matters to me, whether I have time for a good workout or a round of golf, and whether I’m maintaining the relationships that actually bring value to my life.

This isn’t settling or giving up – it’s wisdom. It’s understanding what actually contributes to happiness versus what just looks good on paper.

The hard truth? The things you think matter now might not matter at all in five years. And that’s not a bad thing – it’s growth.

4. Friendships require actual effort

When you’re younger, friendships just…happen. You’re in school together, you work together, you live in the same building. Proximity creates connection.

But as you get older? People move. They have families. Their schedules explode. Everyone’s busy with their own lives.

I’ve watched friendships fade simply because nobody made the effort to maintain them. And I’m guilty of this too. There are people I used to be close with who I haven’t spoken to in years, not because anything bad happened, but because life got in the way and neither of us picked up the phone.

The Harvard Study of Adult Development – one of the longest studies on happiness ever conducted – found that good relationships are the single biggest predictor of happiness and longevity as we age. Not money, not success, not achievement. Relationships.

But here’s the catch: those relationships don’t maintain themselves.

If you don’t actively invest in your friendships, they’ll disappear. And you’ll wake up one day feeling isolated and wondering where everyone went.

5. You realize your parents are just people (with all their flaws)

This one’s tough.

When you’re a kid, your parents seem like they have all the answers. They’re the authority figures who know what they’re doing.

But as you get older, you start to see them as actual humans – complete with fears, insecurities, mistakes, and limitations.

I remember having a conversation with my father where I suddenly realized he was just as uncertain about certain life decisions as I was. He didn’t have some secret wisdom or master plan. He was just doing his best with the information he had.

This realization can be unsettling, sometimes even disappointing. But it can also be liberating.

Your parents did the best they could with what they knew at the time. They weren’t perfect, and that’s okay. Understanding this helps you let go of resentment and accept them as they are.

6. The career ladder isn’t what you thought it was

The career ladder isn’t what you thought it was. 

I spent years in finance, trying to climb the ladder. And I’m grateful for that.

But before I got too far up, I looked at the people ahead of me. The senior guys who’d “made it.” They had the impressive titles, the big salaries, the corner offices.

But they also looked exhausted. Stressed. Trapped in a life that demanded everything from them and gave back…what, exactly? Money? Sure. But they were working eighty-hour weeks, probably missing their kids’ lives, sacrificing their health.

That realization hit me hard. I was looking at my future, and I didn’t want it.
So I made a change. I went into teaching, then eventually into writing and entrepreneurship. People thought I was crazy for walking away. 

The point? Success isn’t a ladder you climb – it’s figuring out what actually matters to you and building a life around that. Sometimes the smartest move is stepping off the ladder entirely before you’ve climbed too high to turn back.

7. You can’t keep everyone happy (and that’s liberating)

For years, I tried to be what everyone wanted me to be. The good employee, the supportive friend, the agreeable guy who didn’t rock the boat.

It was exhausting. And ultimately impossible.

Here’s what I’ve learned in my thirties: you will disappoint people. You’ll make choices others don’t understand. You’ll set boundaries that upset some folks. And that’s okay.

You cannot live your life trying to please everyone. You’ll end up pleasing no one – especially not yourself.

I think about this every time I write something potentially controversial or make a decision that goes against conventional wisdom. Some people won’t like it. Some people will judge. And that’s fine.

The older you get, the more you realize that seeking everyone’s approval is a waste of time. The people who matter will respect your choices, even if they don’t always agree. Everyone else? Their opinion isn’t worth sacrificing your authenticity.

The bottom line

Growing older isn’t easy. Nobody prepares you for the weird mix of wisdom and uncertainty, confidence and doubt, freedom and responsibility that comes with each passing year.

But here’s the thing: despite all these truths, I wouldn’t trade my mid-thirties for my twenties again. Not even close.

Sure, I had more energy back then. Fewer responsibilities. A seemingly endless runway ahead of me.

But I didn’t know myself. I was still trying to be what I thought I was supposed to be, chasing goals that didn’t even align with my values.

Now? I’m more comfortable in my own skin. I know what matters to me. I’m building a life that actually fits who I am rather than who society thinks I should be.

These hard truths aren’t meant to discourage you. They’re meant to prepare you. Because the more you understand about what’s coming, the better equipped you’ll be to handle it with grace.

And maybe, just maybe, you’ll find that growing older isn’t something to fear. It’s something to embrace.
