There may be hope for me yet according to this, but at the moment, I really have no fucking clue what to do.
My early thirties were filled with great ideas for startups. My early fourties are filled with depression that I'm past my prime, don't have the energy, risk tolerance, or money to do a startup, and don't have money to go back to school, so it really doesn't matter what my passion is. Somehow I still need to find a passion and change, though, because my death is impending. Maybe my fifties will be the realization that I am who I am and I'm fine just being bad at everything.
Just because you find a passion, doesn't mean you have to spend money on it. There are an insane amount of free learning resources online (in tech/dev, which I'm assuming what your pro background is). Similarly, I'm seeing an increasing number of bootstrapped startups (they just don't make as much noise as the funded ones).
My twenties were about realizing and coming to terms with the fact that there are people who are smarter, more clever, and more knowledgeable than me. My thirties are about figuring out how to work with these people as much as possible. I do feel that I'm late to the game on this. If I got over my ego earlier and/or had a more collaborative mindset I'd be in a better spot.
Keep looking for that passion. But don't do it alone. Once you find it, it'll be with a group of people "better" than you to help you figure out what to do with it. :)
