I'm also a psychology student, changing careers. Some of it is my own experience in therapy and how amazing that has been. But the real change happened when I volunteered on a hotline. The power of human connection just amazed and thrilled me.
My own therapist made a commitment (in the hippy days) to be a decent, compassionate force in other people's lives. He was going to be an astrophysicist so this was a big switch. The only thing in common is that both fields require curiosity. I think if you don't feel fundamentally curious, you just won't last long in the field. It is not my primary focus but it is a quality that is important and keeps people going.
