“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.”

“Nothing is miserable unless you think it so; and on the other hand, nothing brings happiness unless you are content with it.”

“One must believe in the possibility of happiness in order to be happy, and I now believe in it. Let the dead bury the dead, but while I’m alive, I must live and be happy.”

“The best way to cheer yourself is to try to cheer someone else up.”

“Children are happy because they don’t have a file in their minds called ‘All the Things That Could Go Wrong.’”

“Count your age by friends, not years. Count your life by smiles, not tears.”
