To know oneself, one should assert oneself.

Do not weep do not wax indignant. Understand.

Be gentle to all and stern with yourself.

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

Well done is better than well said.

Either you run the day or the day runs you.

Be thine own palace, or the world's thy jail.

Without hard work, nothing grows but weeds.

It's always too early to quit.
