What is the prinsip for Atheists in their life?

You can even ask that question to people that claim to believe in a god. I mean there are people that believe but don't live for their belief. My friend swears he is christian but I hear that he has gone to church or prayed or anything....

I can't speak for all atheists (since all atheism is is a lack of belief in dieties), but I belive my values and approach to life are a result of my upbringing and culture, and of innate drives in humans (for example the capacity for empathy or a desire to fit in to society). I share many of the same values as believers (such as concern and respect for others) and enjoy life enormously.
