Meaning of Life: Do you Always Think about it? Why?

Thinking of life is usually a waste of time. Great phylosophers tried to solve life's puzzles but died trying to do it. Some people say that everything happens for a reason but what is the reason? What happens when we die? Who is god? 

There are a lot of questions unanswered and unless you plan on going crazy should be left that way.  So yes I used to think of life a lot but stopped becaue I saw it as a waste of my time.
