Do not stop thinking of life as an adventure. You have no security unless you can live bravely, excitingly, imaginatively; unless you can choose a challenge instead of competence.

The very next thing you need to be doing is the thing that terrifies you the most.

Choose a challenge instead of competence

I think that if the atomic bomb did nothing more, it scared the people to the point where they realized that either they must do something about preventing war or there is a chance that there might be a morning when we would not wake up.

The world conspires to help those who are in love with the beauty of their dreams.

If everything was in your favor, if you did not have to surmount any great mountains, then you have nothing to be proud of. But if you feel that you have special difficulties, then you must indeed be proud of your achievement.

The only joy in this hard life is serving others.
