If you're unhappy now, in your 20s, do something about it NOW. I'm in my mid30s, and I doubled down several times on the "generic success" pathway - career, marriage, house.
I am fucking miserable. At this point, I have trouble justifying extracting myself from any of it. If I had just ripped a few bandaids off at 25, I'd be in a way different situation.
Nothing in you is core. If it isn't serving you in a way to get what you truly want, find a new way to interact with the world. No one else will do it for you.
