The belief that youth is the happiest time of life is founded upon a fallacy. The happiest person is the person who thinks the most interesting thoughts, and we grow happier as we grow older.

You must not let anyone define your limits because of where you come from. Your only limit is your soul.

You may deceive all the people part of the time, and part of the people all the time, but not all the people all the time.

When we see beyond self, we no longer cling to happiness.

We must develop and maintain the capacity to forgive. He who is devoid of the power to forgive is devoid of the power to love.

Forgiveness is a process, not a one-time event.

Science is a wonderful thing if one does not have to earn one's living at it.
