Nothing in life is to be feared. It is only to be understood....

I have frequently been questioned, especially by women, of how I could reconcile family life with a scientific career. Well, it has not been easy.

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something and that this thing must be attained.

Leadership is the other side of the coin of loneliness, and he who is a leader must always act alone. And acting alone, accept everything alone.

A leader does not deserve the name unless he is willing occasionally to stand alone.

But no nation can base its survival and development on luck and prayers alone while its leadership fritters away every available opportunity for success and concrete achievement.

Outstanding leaders go out of their way to boost the self-esteem of their personnel. If people believe in themselves, it's amazing what they can accomplish.

Leadership is the art of getting someone else to do something you want done because he wants to do it.

Motivation is the art of getting people to do what you want them to do because they want to do it.

The future belongs to those who believe in the beauty of their dreams.

Always do your best. What you plant now, you will harvest later.

Age is an issue of mind over matter. If you don't mind, it doesn't matter.

Common sense is the collection of prejudices acquired by age eighteen.

The older I grow the more I distrust the familiar doctrine that age brings wisdom.

Wisdom doesn't necessarily come with age. Sometimes age just shows up all by itself.
