Ask HN: How do you figure out what you're passionate about?

I've been in tech for 15 years now. A lot of what I loved about it has changed, and I'm now at a crossroads where I have an opportunity to leave and do something else.

I ended each day of my old jobs exhausted, and never had the energy to do or try the things I thought I was interested in.

I am now in my mid 30s and find myself with a ton of free time. But I am finding I have no idea what I want to do.

Nothing that used to interest me interests me anymore. The things I think I might like I for whatever reason don't have the energy to do or try them.

I feel like I've been in survival mode for so long I dont know what my passions are. How do I find them again?
