I think we have to define happiness here. As for me I have moments of happiness but it doesn't last. Even if everything went perfectly in your life, having people who clearly suffer around you breaks your happiness. So it's very hard to maintain a state of happiness. Blaise Pascal said "Man's greatness lies in his capacity to recognize his wretchedness" and I think I have to agree with this. You also can never predict what is going to happen. You can loose everything very quickly. In fact when somebody ask me "how are you?" Many times I look at my wristwatch and answer "at 9:03 pm (for example), I'm not bad..." because I don't know if everything will go wrong in 5 min from there.
