To know oneself, one should assert oneself.

I can, therefore I am.

Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.

Without hard work, nothing grows but weeds.

Do not weep do not wax indignant. Understand.

The dog that trots about finds a bone.

Well done is better than well said.

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