hey I think its great you have goals. But i dont want you to work out with roids and 3-4 years look at the cover of as muscle mag and give up becuase you still dont look anything like a pro that has been lifting for 10 years with lots of cycles under his belt.
Your better off just taking it one step at a time, mro the long term goal . But for closer goals maybe a local novice show next spring. Then take it from their you might decide to keep going or step on stage say hey its not for you.
I would just say get some kind of higher education .Maybe a tech degree to make money and live on if the bodybuilding thing does not work out or even after your retired from bodybuilding.
I rember hoisting 100lbs of plastic wieghts over my head at age 17 and thinking I wanted to be jack lalanne becuase I saw him do 1000 push ups on tv and swim across a channel with a boat of people tied to his waiste he pulled them for a few miles.Its good to see amazing people do amazing things.Even if its not the mr.o just give it all you have got anyways and be the best you can.
I was kinda tough on you at first .But you got heart kid and might be able to take it pretty far .

just keep on reading and researching your in the right place alot of good guys are here to help you out. If your gonna want the drugs at a better price then your gonna have to hit the more " underground" bodybuilding boards where the action really takes place.
But its all about time .Time is all you have so dont worry about that.
