Never complain and never explain.
If you're going through hell, keep going.
You never know what motivates you.
Be kind whenever possible. It is always possible.
By failing to prepare, you are preparing to fail.
Be thine own palace, or the world's thy jail.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
Only the educated are free.
It's always too early to quit.
A private railroad car is not an acquired taste. One takes to it immediately.
Never be afraid to meet to the hilt the demand of either work, or friendship - two of life's major assets.
