To know oneself, one should assert oneself.

If you think you can do it, you can.

Know or listen to those who know.

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

Without hard work, nothing grows but weeds.

Who seeks shall find.

Do not weep do not wax indignant. Understand.

If you've got a talent, protect it.

By failing to prepare, you are preparing to fail.
