If you're unsure about the field, I would suggest getting some experience in it. Try to land a tech job, or even just volunteer/shadow at a pharmacy, see what it's all about. The classes and the schools won't give you nearly as good of an idea on whether this is something you want to do.
Heartily seconded! If you need some advice on how to go about it, there are a lot of certified people here who can tell you where to go to get your licensure. (I'm in AZ - if that's where you happen to be, I'd be happy to point you to some resources.) I found it useful to have already taken Gen Chem II, but if you took high school chemistry and really "got it," or have good study skills and motivation, you should be just fine.
My reasons? In no real particular order:
1) The money. The only three ways to get ahead are a) school, b) luck, c) "the next big thing." My mum has been trying to invent the "next big thing" for as long as I can remember, and it hasn't worked yet. Oh, I also buy Lotto tickets.
2) Flexible working environment. I really haven't figured out what work environment suits me best, so having many options is good. (Electrical Engineering, my previous major? Not as much.) You can work retail, pbm (checking scripts or phone work), hospital, administration (drug & insurance companies)... Those are just what I can think of off the top of my head. Oh yeah! Radiopharmacy, too.
3) I like to constantly learn new things. I get bored when I get in a rut. Pharmacy is a field in which you can constantly learn about new things - If you manage to have your fill of learning about drugs for the moment, there are so many subjects tangential to Pharmacy that I can't even imagine getting to the end of what would interest me!
4) While I'm sure I could handle bodily fluids, the option of having the above three items met without having to do physical hard labor or cleaning up infectious liquids is good.
5) Respect. Nobody in my family has above a Master's (and even that's in French... and her kids don't speak French. What a waste). Plus, as someone mentioned above, the mysteriously sleeveless white coat.
I'm sure I can think of more, but this verges on being a novella already.
