The research career is hard in a way that’s not often talked about. It’s not just intellectually difficult — it’s personally difficult. It functions a lot like entrepreneurship. You are left entirely to your own demise. You have near-total autonomy, and what that does is amplify whatever your default tendencies are.

If you are a high-anxiety person — which describes a large number of successful researchers — you will likely internalize everything. You’ll obsess, push harder, and feel like the world will fall apart if you don’t accomplish something today. That’s often why people succeed. But it also means you can burn yourself out or break down completely. The anxiety becomes the thing that eats you alive.

On the flip side, if you are naturally more relaxed or chill, it’s easy to default to avoidance. You just won’t get much done. You tell yourself it’ll be fine — and nothing happens. And nobody is really there to push you, because there’s nobody watching.

The whole system reinforces whatever your crutch is. If you’re prone to loneliness, you’ll feel it more. If you’re prone to overwork, you’ll overwork. If you need structure, there isn’t any. And over time, it becomes clear that the hardest part isn’t the research — it’s regulating your own head.

Most of the damage comes from being left to your own psychology. And that’s what makes the research profession so much like building a startup. It’s rarely about your ideas. It’s whether you can survive being left to yourself.
