"The most important persuasion tool you have in your entire arsenal is integrity."
- Zig Ziglar

"Integrity is telling myself the truth. And honesty is telling the truth to other people."
- Spencer Johnson

"Real integrity is doing the right thing, knowing that nobody's going to know whether you did it or not."
- Oprah Winfrey

Why is discipline important? Discipline teaches us to operate by principle rather than desire. Saying no to our impulses (even the ones that are not inherently sinful) puts us in control of our appetites rather than vice versa. It deposes our lust and permits truth, virtue, and integrity to rule our minds instead."
- John MacArthur

"Integrity is the foundation upon which all other values are built."
- Brian Tracy

Seems to say the same thing as Proverbs 10:9 in the Holy Bible....

"With integrity you have nothing to fear, since you have nothing to hide. With integrity you will do the right thing, so you will have no guily. With fear and guilt removed you are free to be and do your best."
- Zig Ziglar
