Happiness is an inside job. Don't assign anyone else that much power over your life. - Mandy Hale
Happiness should always come from within, you hold the power to your own happiness.
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. - Groucho Marx
Happiness is not something ready made. It comes from your own actions. - Dalai Lama
It is not how much we have, but how much we enjoy, that makes happiness. - Charles Spurgeon
