There is always something to chuckle about. Sometimes we see it. Sometimes . . . we don't. Still, the world is filled with humor. It is there when we are happy and it is there to cheer us up when we are not.
Your attitude is like a box of crayons that color your world. Constantly color your picture gray, and your picture will always be bleak. Try adding some bright colors to the picture by including humor, and your picture begins to lighten up.
