7. John D. MacDonald Quote
As once opined by John D. MacDonald (1916-1986), Integrity is not something conditional. It doesn’t change with weather nor doesn’t it get blown in the air. Integrity is an inner image of you, and if look in there and in the process see a man who won’t cheat, then be assured he will never cheat. This quote is mainly famous when it comes to integrity issues. Most people consider this quote as one of the famous quotes ever.
