Albert Schweitzer

A great secret of success is to go through life as a man who never gets used up.

A man can do only what he can do. But if he does that each day he can sleep at night and do it again the next day.

A man does not have to be an angel in order to be saint.

A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help.

A man is truly ethical only when he obeys the compulsion to help all life which he is able to assist, and shrinks from injuring anything that lives.

An optimist is a person who sees a green light everywhere, while a pessimist sees only the red stoplight... the truly wise person is colorblind.

Anyone who proposes to do good must not expect people to roll stones out of his way, but must accept his lot calmly, even if they roll a few stones upon it.

As soon as man does not take his existence for granted, but beholds it as something unfathomably mysterious, thought begins.

At times our own light goes out and is rekindled by a spark from another person. Each of us has cause to think with deep gratitude of those who have lighted the flame within us.

By having a reverence for life, we enter into a spiritual relation with the world By practicing reverence for life we become good, deep, and alive.

Do something for somebody everyday for which you do not get paid.

Do something wonderful, people may imitate it.

Ethics is nothing else than reverence for life.

Ethics is the activity of man directed to secure the inner perfection of his own personality.
