Know or listen to those who know.

The secret of getting ahead is getting started.

By failing to prepare, you are preparing to fail.

Wherever you are - be all there.

The dog that trots about finds a bone.

Begin to be now what you will be hereafter.

Go for it now. The future is promised to no one.

It's always too early to quit.

To know oneself, one should assert oneself.
