Passion?

Suddenly, I had a really big brainstorming moment. I just thought about myself and maybe it's a little philosophical and boring. What's my point? For what I was into this world? I won't be a useless person! It just came up after I was asked to make a motivation letter, what's motivating me? God! This harder than answering statistical questions. Anyway, I know that none couldn't answer this thing except my self. But, writing this down a little bit helping me reduce my burden. Bloggers, how can you find what's your motivation? Geez! I need psychologist...
