“Take into account that great love and great achievements involve great risk.”

All suffering is caused by ignorance.

There are only two days in the year that nothing can be done. One is called Yesterday and the other is called Tomorrow.

True change is within; leave the outside as it is.

The way to change others’ minds is with affection, and not anger.

Whether one is rich or poor, educated or illiterate, religious or nonbelieving, man or woman, black, white, or brown, we are all the same.

Give the ones you love wings to fly, roots to come back and reasons to stay.

An eye for an eye. We are all blind.

If someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun.

The very purpose of our life is to seek happiness.

Our prime purpose in this life is to help others. And if you can’t help them, at least don’t hurt them.

An open heart is an open mind.

If I am only happy for myself, many fewer chances for happiness. If I am happy when good things happen to other people, billions more chances to be happy!

A disciplined mind leads to happiness, and an undisciplined mind leads to suffering.

We can never obtain peace in the outer world until we make peace with ourselves.

Because we all share this planet earth, we have to learn to live in harmony and peace with each other and with nature. This is not just a dream, but a necessity.

It is not enough to be compassionate, we must act.

Unless you try to do something beyond what you have already mastered, you will never grow. Every job is a self portrait of the person who did it. Autograph your work with excellence.

To achieve something you have never achieved before you must become someone you have never been.

A man ought not to value himself of his achievements or rare qualities of wit, much less of his riches, virtue or kindred.

Desire is the starting point of all achievement, not a hope, not a wish, but a keen pulsating desire which transcends everything.

Achievement has no color.

Criticism is easy; achievement is difficult.

There seems to be an attitude problem, as if we cannot shake ourselves out of a mindset of limited achievement.

I believe that the message of Apollo XI was that in the spirit of Apollo, a free and open spirit, you can attack a very difficult goal and achieve it, if you can all agree and work together to achieve that goal.
