If you think you can do it, you can.
Know or listen to those who know.
You never know what motivates you.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
Well done is better than well said.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
The principles we live by, in business and in social life, are the most important part of happiness.
