Psychology?

I've gotten "psychology?" with a definite change in the voice often the last few days.  How in the world was I supposed to draw a line from working in a bank for more than six years to the strong desire to analyzing people's minds?  Each time I answered it sounded something like this: "I want to help kids, I want to help them get through tough times & losing loved ones & dealing with physical disabilities."  And you know what?  Each of them five-ish times I said that answer, I felt more like it was what really was deep in my heart & what I *WILL* do someday.
