My feeling is that to be an effective therapist, psychologist or psychiatrist, you have to care about the people you treat. I'm sure there are exceptions, but I don't know how much you could accomplish if you treated your patients just as assignments. If you care about people, you'll feel their pain and it will wear on you. You need to be dedicated and strong emotionally. In my efforts at counseling students, I've found that I get submerged in their struggles and can't bring myself to treat their issues casually. It ends up taking a lot of emotional effort, at least for me. I had one student tell me in the middle of a lecture I was giving in China right in public that I changed his life. Now if that's not a nice moment, I don't know what is. That kind of thing makes just about any effort worth it. If you want to go into any of these fields, let your heart be your guide. It sounds corny, but trust me -- you'll know if it's right.
