What Do You Live For?

This is Emily, I am from China. I am a new graduater. I work as a foreign trade businessman in a  company. During this period, I often asked by meself, what do I love for ?

I think I live for dream, for make sure my value. Now in order to make my dream true, I have to endure no weekend's Day and live alone in a strange environment. Then more than one months has passed, i haven't  found my first customer. I don't know how should I do ?
