career advice please (esp. lawyers, but all advice appreciated)?

[Kristy]

So i'm in high school, 16 years old. I know you dont HAVE to map out your life this young, but i've been thinking about it a lot because no career has stood out in my mind. however, after a lot of research lately, law has interested me. i feel like i could be a very good lawyer. in-house lawyers look especially appealing to me.
Basically, i feel like i could be good at this for a few reasons. I'm pretty smart (ranked 3rd in my class of about 130). I'm very organized, responsible, a good learner, great leader (class president, interact club president...), and i really love to speak in front of others. I'm best in the science,math, history fields, but i dont want to work in a lab all day or just putting numbers in a calculator all day.
The drawbacks to this are as follows. I dont know if i could handle all that time in college. I dont know if i'm smart enough for it. I really want to get married and raise children and i dont want it to interfere. cont..
so please, i would appreciate if someone with experience in law could tell me what its like to be a lawyer, and what you need to be cut out for it. also, i would love any other ideas you have about alternate careers if you dont think this is for me. thank you veryyyy much!
