To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

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

If you've got a talent, protect it.

Be kind whenever possible. It is always possible.

You never know what motivates you.

Without hard work, nothing grows but weeds.

Never complain and never explain.
