I can, therefore I am.

You can't wait for inspiration. You have to go after it with a club.

Only the educated are free.

You are not here merely to make a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world, and you impoverish yourself if you forget the errand.

Small deeds done are better than great deeds planned.

Wherever you are - be all there.

No matter how many goals you have achieved, you must set your sights on a higher one.

To be wholly devoted to some intellectual exercise is to have succeeded in life.

To be a good loser is to learn how to win.

Without hard work, nothing grows but weeds.
