What is the purpose of our life?

Sometimes I have to ask myself that what do I want for my life. And it turnout I could not give myself an answer. I did study hard when I was a student, I did work hard when I was an employee. But they don't mean much to my life, because they are juts part of everyone's life, it is not something I particular look for.  Well, after few times tries, I finally give up and not try to figure out what I want, instead of trying to figure out how to make my life better. By maing my life better I mean make myself feel better, make myself treat better, make myself more comfortable, make myself less worry. So now live a life is the purpose of my life.
