hello,
I also have a psychology degree.
psychology is good for knowing how to manage a team as well as knowing how to type people and characters.
I don't know how to program or do art either, but I've found I'm good at management coordination, research, and writing.
And I co lead an indie studio.
So best thing to do is to start putting down your ideas in an organized fashion. Draft up your ideas, the more detailed the better. Games need writers, so you can do that. plan out your game. then once you have the core idea down, you can look for a team. or start a team.
