Never complain and never explain.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
If you're going through hell, keep going.
Well done is better than well said.
You never know what motivates you.
It's always too early to quit.
Only the educated are free.
Do not weep do not wax indignant. Understand.
By failing to prepare, you are preparing to fail.
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.
