Why Your Side Hustle Is Draining You (And What You're Missing)

There's this pattern that comes up again and again in conversations with people who've built something on the side — a blog, a freelance practice, a YouTube channel. They started it with a kind of energy their day job didn't give them. And somewhere along the way, it started feeling heavier than the day job itself.

That's not a coincidence, and it's not about willpower.

The "slash career" concept — designer slash developer, engineer slash podcaster — was supposed to represent a second identity. Something yours, outside the org chart and the performance reviews. Something you actually chose.

The problem is what happens to that "something you chose" over time.

Psychology has a useful framework called Self-Determination Theory. It identifies three things humans genuinely need to feel good about what they're doing: autonomy — the sense that you chose this, not that it was imposed on you; competence — the feeling that you're growing; and relatedness — feeling connected to people or to something that actually matters. Most side projects get started because a main job is failing on one of those fronts. No autonomy at work. No visible growth. Technically fine job that feels weirdly hollow. The side project fills that gap.

Here's where it goes sideways.

In the beginning, you have high autonomy. You write when you want to write. You experiment because it sounds interesting. Even if it takes hours, it doesn't feel draining — because you chose it. That choice is the whole point.

But then the side project starts developing its own rules. Post on a schedule because the algorithm rewards consistency. Hit a revenue target because "if I'm spending this much time on it, I should at least be making something." Start comparing numbers with peers in the same space. Suddenly the thing that was supposed to give you autonomy is being run by external pressure. You're not writing because you want to — you have to keep the schedule. You're not teaching because you find it interesting — you need to keep enrollment up.

The autonomy disappeared. The workload didn't. Of course it's exhausting.

How this plays out depends on why you started in the first place. If your main job is suffocating and the side project is your planned exit, that structure works — until it doesn't. If you never actually fix what's wrong at work, the side project gradually absorbs the same pressure, and you end up stressed on two fronts instead of one.

If you started for income, it's actually more stable than it sounds. The goal is defined, the finish line is visible. The main risk is slow-burning frustration if the money stays low for a long time.

If you started for something like self-actualization — genuinely moving in a direction you care about — that's the hardest to sustain but potentially the most satisfying. The tricky part is that this kind of goal has no finish line. It expands to fill whatever space you give it. Which means without intentional structure, it just keeps growing.

A few questions worth sitting with honestly.

If this never made any money, would you keep doing it? If the answer is no, that's fine — but it means you have a second job. Treat it like one, with real boundaries and finite investment.

After you work on it, do you feel more energized or more depleted? Consistently depleted is a signal the current form isn't working, regardless of what it used to feel like.

And when did you last genuinely enjoy the process? Loss of playfulness is usually the first thing to go when obligation has quietly replaced actual interest.

Here's the part that sounds like heresy in a productivity-obsessed culture: a side project doesn't have to be productive.

If the whole point is to fill a gap your job doesn't fill, then filling that gap is the win. You don't need a YouTube channel to do that. You don't need a Substack. A private blog, a skill you're learning purely for the sake of it, an interest group you joined because you were curious — those all count. What matters is whether that space is helping you stay a fuller version of yourself than your job alone allows.

So before you stress about your content calendar or your growth metrics, it might be worth asking a simpler question: is this thing still yours?

Three things to take away. First: side hustles burn people out when external pressure replaces internal motivation — when "I want to" quietly becomes "I have to." Second: the type of side hustle changes how it fails, but the failure mode is usually the same — autonomy drops while the workload stays. And third: a side project that doesn't produce income or audience growth isn't failing. If it's keeping you more whole, it's doing exactly what it was supposed to do.
