hI. do what you feel is best, if you can run really fast and you think you are capable of a world class time, go ahead for it. make sure you are at athletics clubs and stuff. if you want to be a lawyer that cool but it would only be half as fun as being an olympic, winning medals and you could be famous. it's up to you but i'd say an olympian, you'd be famous, more wealthy and would be representing your country.
