To know oneself, one should assert oneself.

I can, therefore I am.

Know or listen to those who know.

Begin to be now what you will be hereafter.

If you've got a talent, protect it.

Do not weep do not wax indignant. Understand.

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

If you think you can do it, you can.

Only the educated are free.
