People who are unable to motivate themselves must be content with mediocrity, no matter how impressive their other talents.

Keep your eyes on the stars, and your feet on the ground.

We are all motivated by a keen desire for praise, and the better a man is, the more he is inspired by glory.

To succeed in your mission, you must have single-minded devotion to your goal.

Neither seek nor avoid, take what comes.

Your pain is the breaking of the shell that encloses your understanding.

If you enter this world knowing you are loved and you leave this world knowing the same, then everything that happens in between can be dealt with.

Change your thoughts and you change your world.

People who say it cannot be done should not interrupt those who are doing it.

You have brains in your head. You have feet in your shoes. You can steer yourself any direction you choose.

The fact that the great scientist believed in flying machines was the one thing that encouraged us to begin our studies.

However many holy words you read, however many you speak, what good will they do you if you do not act on upon them?

Knowing what's right doesn't mean much unless you do what's right.

You'll never get ahead of anyone as long as you try to get even with him.

Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.

The best way to find yourself is to lose yourself in the service of others.

Whatever you are, be a good one.

Isn't it astonishing that all these secrets have been preserved for so many years just so we could discover them!

We travel. Some of us forever. To seek other states, other lives, other souls.
