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

Know or listen to those who know.

It's always too early to quit.

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

Do not weep do not wax indignant. Understand.

If you think you can do it, you can.

Always desire to learn something useful.

Never complain and never explain.
