“I think it’s perfectly okay to realize that not every day will be great — or even good — but I don’t think it’s okay not to at least give every day a chance.”

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.
