If you observe a really happy man you will find him building a boat, writing a symphony, educating his son, growing double dahlias in his garden. He will not be searching for happiness as if it were a collar button that has rolled under the radiator.- W. Beran Wolfe
Ah, literally doing and living life not just looking for something that may or may not be there. There is a lot to be said for just going out and living. Keeping busy, helping others, looking at nature. Kind of not only makes you happy, but keeps you from thinking about being unhappy.
We can't do that a 100% of the time. There is a time to be happy and a time to be unhappy. Take your time to be unhappy. Deal with it . Look it over. Then sometimes even when you don't feel like it, DECIDE to move on towards happiness.
Get busy. :)
