To know oneself, one should assert oneself.

I can, therefore I am.

Begin to be now what you will be hereafter.

Do not weep do not wax indignant. Understand.

The dog that trots about finds a bone.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

Know or listen to those who know.

Without hard work, nothing grows but weeds.
