What brings you inner peace and purpose in life?

For me there are a few people / things which gives me a purpose of life. They are:

My mother's smile! Yeah that smile which comes to her face while telling others about my achievement.My dreams! A lot many dreams has been there in my eyes! Some dreams are such which very few dare to chose! And as my dreams are rare giving me a clear goal, gives me inner peace.My father's hardwork: For what my father work? For me! Obviously then it's my responsibility to fulfil his dreams!
