If you think you can do it, you can.

If you can dream it, you can do it.

Be gentle to all and stern with yourself.

It's always too early to quit.

Without hard work, nothing grows but weeds.

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

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

Well done is better than well said.

To know oneself, one should assert oneself.
