To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

I can, therefore I am.

Always desire to learn something useful.

It's always too early to quit.

If you think you can do it, you can.

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