What you do today can improve all your tomorrows.
It's always too early to quit.
Be kind whenever possible. It is always possible.
You never know what motivates you.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
Quality is not an act, it is a habit.
Only the educated are free.
If you're going through hell, keep going.
Always desire to learn something useful.
People who think my books are autobiographical, which they're not, credit me with having a much better memory than I do. I do, however, have a powerful imagination.
