motives

why do i do what i do, what motivates me. i think if i look back at most of my actions, the big ones are motivated because of rather stupid reasons. mostly i am motivated by popularity, and the acquiring of friends. i am thinking about my trip around the world and wondering what exactly my motivations are, i dont think that its to make friendships, but i do think i am partly doing it for the esteem of others, as well as braging rights of "hey i did this". i am not sure if someone can do something out of a pure motivation. i think because we are all basicly selfish deep down everything we do will on some level, no matter how selfless, will be on some level for our own gratification.
