why do you fail?

I fail because I don't try hard. Sometimes I never even tried. Sometimes I'm simply not interested. Other times I think what I'm supposed to do is stupid and avoid doing it over all. There are times I tried and fail, and those are the times that I remember most. Failing after giving everything I've got is disappointing, but it shows me my weaknesses and would make me want to improve.

I fail because i don't have a right attitude to meet chanllge.just like a famous saying "attitude is everything" .when i meet some difficulties,i just complain ,not to try my best.in other words,i don't want to be the No 1 ,that the reason that i fail.
