Well done is better than well said.

Do not weep do not wax indignant. Understand.

Be gentle to all and stern with yourself.

Without hard work, nothing grows but weeds.

If you think you can do it, you can.

You never know what motivates you.

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

To know oneself, one should assert oneself.

It's always too early to quit.
