Follow a dream?or notttttttttttttttttttt?

alright im a 17 year old guy with a potentially bright future ahead of me. I will be a senior in high school and am supposed to become a doctor or lawyer. However, I have rethought the entire situation and realized that I dont want to be Normal. I wnat to do somehting sporadic with my life to try to reach my dreams. Thus, Im currently thinking of starting some sort of business after college or even during it. I have been saving my money up for a while and have saved up 10 grand. Any tips people?
