My life is going so many places... so how come i feel like throwing it all away?

I am really good at a sport and will probably get a scholarship... I'm pretty smart school-wise and street-wise... I have a lot of friends and I'm very attractive but I always find myself wanting a more exciting life.. I'll read books about crystal meth and even though it shows all the horrible things about substance abuse, I still find myself curious and wanting a taste... I feel like being "bad" will be more liberating and exciting then being "good"... So basically I'm asking what I should do about these feelings...
