So do you want somebody to tell you that you CAN'T do it? Or that you COULD do it, but based on prior experience, they dont think you will? My mother thinks thats how to motivate someone, make them mad so they want to succeed just to prove you wrong. Personally i find it undermining, especially if they laugh at you and look at you with crazy eyes.

What do you really WANT to do? I'm trying to answer this question for myself.
