Know or listen to those who know.

By failing to prepare, you are preparing to fail.

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

Either you run the day or the day runs you.

Things do not happen. Things are made to happen.

Wherever you are - be all there.

Begin to be now what you will be hereafter.

Be thine own palace, or the world's thy jail.
