To know oneself, one should assert oneself.

Always desire to learn something useful.

I can, therefore I am.

If you think you can do it, you can.

It's always too early to quit.

What you do today can improve all your tomorrows.

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

Know or listen to those who know.

Do not weep do not wax indignant. Understand.
