People are really concerned about money, money, money. But, in my opinion, working for yourself to achieve your own vision is so fun.. and this is on what I put emphasis when people around me don't understand why I don't work for a big company or something.
So, instead of saying, I might be the next facebook, or I will make 100x more then you, or whatever concerning money, I usually just say, I never had so much fun in my life and I wouldn't never go back to a "normal" job again. : )
