My degree is in psychobiology - it's a B.A. not a B.S. I find psychology/psychobiology to be really interesting, but I don't want a career out of it. I like helping people, but I don't want to be a therapist - I think I would be overly involved and get too upset over it. It's a lot of responsibility. I like that in pharmacy there are definite right and wrong answers - this medication will interact with that, etc. It's more clear-cut and more my personality than psychology.
Not to mention that a degree in psych without a Master's or PhD is bleak, career opportunity wise. I went to an interview where they told me I'd be getting $10/hour, have to drive severely mentally ill people in my own car, and I *probably* won't get murdered. I decided for that money, I'd rather try to be a pharm tech and see what happens. It turns out I really like retail pharmacy so I took my prerequisites and applied to pharmacy school.
