Well done is better than well said.
Quality is not an act, it is a habit.
If you think you can do it, you can.
Always desire to learn something useful.
The wise does at once what the fool does at last.
Either you run the day or the day runs you.
It's always too early to quit.
Be kind whenever possible. It is always possible.
The most effective way to do it, is to do it.
Know or listen to those who know.
If someday they say of me that in my work I have contributed something to the welfare and happiness of my fellow man, I shall be satisfied.
