You never know what motivates you.

Know or listen to those who know.

The secret of getting ahead is getting started.

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

To know oneself, one should assert oneself.

Do not weep do not wax indignant. Understand.

Begin to be now what you will be hereafter.

Be gentle to all and stern with yourself.

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