To know oneself, one should assert oneself.

Know or listen to those who know.

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

It's always too early to quit.

To be a good loser is to learn how to win.

The dog that trots about finds a bone.

Without hard work, nothing grows but weeds.

What you do today can improve all your tomorrows.

Do not weep do not wax indignant. Understand.
