Happiness UnLTD

 I realized happiness does not depend on circumstance; it depends on you, and in there is your free will. That is what no amount of 'out of control' can ever take away from you. How you feel depends on how you choose to feel and that determines how you perceive life and how it affects you.

So it doesn't matter if you are not rich, if you are not young, if you are alone, it doesn't matter. You are as happy as you choose to be.
