What is REAL happiness??

Happiness for me is the pursuit of a dream, I'm still young, and I want to make the best of my life. I don't want to live a normal life, but really mean something. My dream is to become brain surgeon. It is a way to be somebody in the meaning of helping people and having a great responsibility. I want my life to be perfect, of course some troubles, but nothing serious. I want to live my life in a quiet and peaceful way, in a great place and with great people. That's my definition of pursuit of happiness, my way of dreaming.
