If I am happy in spite of my deprivations, if my happiness is so deep that it is a faith, so thoughtful that it becomes a philosophy of life. If, in short, I am an optimist, my testimony to the creed of optimism is worth hearing.

The highest thinkers of the ages, the seers of the tribes and the nations, have been optimists.

My life has been happy because I have had wonderful friends and plenty of interesting work to do.

God doesn't promise security from life's storms but security in life's storms. God doesn't always call the equipped, but he will always equip the called. In the long run, avoiding danger is no safer than outright exposure. The fearful are caught as often as the bold.

We should not think of conversion as the acceptance of a particular creed, but as a change of heart.

The struggle of life is one of our greatest blessings. It makes us patient, sensitive, and Godlike. It teaches us that although the world is full of suffering, it is also full of the overcoming of it.

Your success and happiness lie in you.
