Do not weep do not wax indignant. Understand.

What you do today can improve all your tomorrows.

Always desire to learn something useful.

If you think you can do it, you can.

To know oneself, one should assert oneself.

The wise does at once what the fool does at last.

It's always too early to quit.

I can, therefore I am.

Be gentle to all and stern with yourself.
