Present

something to ponder upon? 

"Yet you look to the future to make you happy. I’ll be happy, you say, when I’m married. Then, after you get married, you think, I’ll be very happy when we have children. Of course, when you have kids you can’t enjoy yourself without a house. You postpone your happiness until that perfect future date, but it never arrives."-pike

I guess happiness means being/LIVING in the present moment. As if you're going to die tomorrow. Forget about the past and don't think of the future coz it holds no promises.
