To know oneself, one should assert oneself.

The dog that trots about finds a bone.

Without hard work, nothing grows but weeds.

Never complain and never explain.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

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

Do not weep do not wax indignant. Understand.

It's always too early to quit.
