When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us.
-Helen Keller
Human felicity is produced not so much by great pieces of good fortune that seldom happen as by little advantages that occur every day.
-Benjamin Franklin
Do not seek to have everything that happens happen as you wish, but wish for everything to happen as it actually does happen, and your life will be serene.
-Epictetus
It is a dangerous thing to ask why someone else has been given more. It is humbling--and indeed healthy--to ask why you have been given so much.
-Condoleezza Rice
We must develop... the capacity to forgive. He who is devoid of the power to forgive is devoid of the power to love. There is some good in the worst of us and some evil in the best of us. When we discover this, we are less prone to hate our enemies.
-Martin Luther King Jr.
The utmost we can hope for in this world is contentment; if we aim at anything higher, we shall meet with nothing but grief and disappointment.
-Joseph Addison
All fortune belongs to him who has a contented mind. Is not the whole earth covered with leather for him whose feet are encased in shoes?
-Panchatantra
