There's no better time to be happy than right now.
Your life will always be filled with challenges. It's best to admit this to yourself and decide to be happy anyway.
There is no way to happiness. Happiness is the way. So, treasure every moment that you have.
Stop waiting until you finish school, until you go back to school, until you lose ten pounds, until you gain ten pounds, until you get married, until you have kids, until your kids leave the house, until you start work, until you retire, until spring, until summer, until fall, until winter, until you are born again to decide that there is no better time than right now to be happy.
