Well, Mr_Mischif, let me start by giving you this qoute:
"Keep away from people who belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great."

-Mark Twain

Now tho, the reasoning behind them saying you'd fail may be valid, you do what you feel you wanna do. There's always exceptions to every rule, it's the little people with big dreams who succeed.

Now I'm not shytting on the people who posted that he'd fail. I'm simply saying, that's the main reason alot of people never make it, people not beleiving in themselves/idea's. Goofier shyt has suceeded in the past : The pet rock, The chia pet, hell even the clapper.

Now granted, you could fail, but is it better to try & maybe be successful, or listen to others, not try & wonder "what if"? I'd advise researching, & man if you feel it in your heart DO THE DAMN THING, & don't look back. .....Vegeta
