Happiness is a really hard thing to explain, you feel happiness when you are with the people you like, do things you like, when you see something you like. You smile when your happy and also when you sense freedom. Freedom comes in many ways, when you can do something you like without people telling you what to do or stopping you from. Being free is having one's own opinion to make one's own decision. Also, you have to have courage to take the decisions, to move forward, to innovate. You are courageous when you do something you are afraid of, or other people are afraid of, to face to unknown, to fight something stronger than you.
