Sam, don't be discouraged if you can't decide what you want to be for a long time. i always felt so pressured as to what i wanted to be, but could never decide. in 11th grade i almost ended it all because i still didn't see a future for myself and i lived in an abusive home. but then i met the right person who loved me for me and sheltered me the best he could. after i graduated i got a finally got a job, but still had no idea what i was going to do w/ my life. i was getting soooo miserable. in the fourth or fifth month of my job, i finally found out what i was going to do w/ my life. one and a half years after i graduated!
the point is, is don't give up, and don't get discouraged.
