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.

All serious daring starts from within.

Everything that is excellent will come when this sleeping soul is aroused to self-conscious activity.

We must always take sides. Neutrality helps the oppressor, never the victim.

Keep in mind always the present you are constructing.

Don't be afraid to face the facts, and never lose your ability to ask: Why? and How?

The goal of all our actions is to be free from pain and fear.
