To know oneself, one should assert oneself.

If you think you can do it, you can.

Well done is better than well said.

Only the educated are free.

Do not weep do not wax indignant. Understand.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

The most effective way to do it, is to do it.

The dog that trots about finds a bone.
