Why change your world?

When you are happy with your life, why do you go out of your way to change it?

I am thankful for my life but I have this consent thought about ways of changing it. I hoping to find my way through some hard times, by finding work for myself. Its weird, I am trying to find work for myself so later I do not have to work?

This idea or process has been in my mind ever since I starting to be conscience of my actions. Is this what everyone else feels or is this just my personality trait?
