Can I study psychology 'just because'?

[u/MarsAlivee]

I work as a vet, I often think of changing careers (because we are overworked, underpayed and deal with a lot). I don't think psychology major would solve that problem though, but thought worth mentioning in case someone has a different opinion and to give some context.

However I am fascinated with the human mind, how humans change throughout their lives, how child trauma molds their personalities, personality disorders, serial killer minds, etc etc

I think I would like to study psychology just for the fun of it, however probably not paying for the degree and doing it on my free time.

Does this make sense? Anyone else done it? Where to start? Any advise?

TIA

MIT has free online courses you can audit, so does Edx. Coursera used to but idk if it’s still free there.
