Anyone know a good book to choose career? I heard of something called What Color is Your Kite. I can't find...?

I don't want anything sappy, but something to give me direction. I'm 27, worked in a few different areas of business and haven't found true pion that also matches my talents. Want to do path switch with some post-college education but make a good choice...considering pharmacy, accounting, consulting, actuarial work, high school math teaching...very confused.
