Be gentle to all and stern with yourself.

Expect problems and eat them for breakfast.

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

It's always too early to quit.

Know or listen to those who know.

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

Go for it now. The future is promised to no one.

Leap, and the net will appear.

Without hard work, nothing grows but weeds.
