motivation

i think people have different ambition. Some people say that they just want to work and be somebody in life because they think that owned to their parents. other just want to be better than their friends and family.In other words competition is their motivation. But i believe that the reason most of the people work hard for, is because it feels good when you get something that causes you a lot of sacrifices to obtain. At least thats what motivate me.the feeling that you get after accomplishing something that was a really a hard task is what push you to give the best of you and try to surpass your own limits.
