Know or listen to those who know.

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

It's always too early to quit.

Either you run the day or the day runs you.

By failing to prepare, you are preparing to fail.

Be kind whenever possible. It is always possible.

Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

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