Push yourself to be happy. Make it a goal and work at it. Fake being happy until you are happy. It is an attitude and something that you decide. Count all of your blessings and realize that you have a lot to be happy about. You might have a lot to be sad about but consider the glass half full and not half empty-be happy.
Consider the quote from Spencer Kimball, Happiness does not come by pressing a button, as does the electric light; happiness is a state of mind and comes from within. It must be earned. It cannot be purchased with money; it cannot be taken for nothing.
You deserve to be happy-and it's always just one choice away.
