To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

Never complain and never explain.

Things do not happen. Things are made to happen.

What you do today can improve all your tomorrows.

Wherever you are - be all there.

Quality is not an act, it is a habit.

I can, therefore I am.

The wise does at once what the fool does at last.
