What you do today can improve all your tomorrows.
Be kind whenever possible. It is always possible.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
Know or listen to those who know.
Always desire to learn something useful.
If you're going through hell, keep going.
The secret of getting ahead is getting started.
Never complain and never explain.
Without hard work, nothing grows but weeds.
One reason the human race has such a low opinion of itself is that it gets so much of its wisdom from writers.
