Be gentle to all and stern with yourself.

I can, therefore I am.

It's always too early to quit.

Things do not happen. Things are made to happen.

Either you run the day or the day runs you.

Do not weep do not wax indignant. Understand.

Wherever you are - be all there.

Quality is not an act, it is a habit.

To know oneself, one should assert oneself.
