Be gentle to all and stern with yourself.

Know or listen to those who know.

If you're going through hell, keep going.

By failing to prepare, you are preparing to fail.

Problems are not stop signs, they are guidelines.

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

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

If you can dream it, you can do it.

Without hard work, nothing grows but weeds.
