To know oneself, one should assert oneself.

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

I can, therefore I am.

Know or listen to those who know.

What you do today can improve all your tomorrows.

Always desire to learn something useful.

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.
