Each morning when I open my eyes I say to myself: I, not events, have the power to make me happy or unhappy today. I can choose which it shall be. Yesterday is dead, tomorrow hasn't arrived yet. I have just one day, today, and I'm going to be happy in it.
Being happy doesn't mean you're perfect. It just means you've decided to look beyond the imperfections.
If you think sunshine brings you happiness, then you haven't danced in the rain.
"A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort."
