Know or listen to those who know.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
Begin to be now what you will be hereafter.
The wise does at once what the fool does at last.
It's always too early to quit.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
Be thine own palace, or the world's thy jail.
Be thankful for problems. If they were less difficult, someone with less ability might have your job.
