Know or listen to those who know.

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

If you're going through hell, keep going.

Be kind whenever possible. It is always possible.

Never complain and never explain.

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

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

Begin to be now what you will be hereafter.
