Self-respect speaks...

1. If you want to be respected by others the great thing is to respect yourself. Only by that, only by self-respect will you compel others to respect you. ~Fyodor Dostoyevsky
2. Respect yourself and others will respect you. ~Confucius
3. Self-respect is the cornerstone of all virtue. ~John Herschel
4. Respect for self is the beginning of cultivating virtue in men and women. ~ Gordon B. Hinckley
5. That you may retain your self-respect, it is better to displease the people by doing what you know is right, than to temporarily please them by doing what you know is wrong. ~William J.H. Boetcker
6. Never esteem anything as of advantage to you that will make you break your word or lose your self-respect. ~ Marcus Aurelius
7. Respect your efforts, respect yourself. Self-respect leads to self-discipline. When you have both firmly under your belt, that's real power. ~Clint Eastwood
8. Self-respect is the fruit of discipline; the sense of dignity grows with the ability to say no to oneself. ~Abraham J. Heschel
9. Respect for ourselves guides our morals; respect for others guides our manners. ~Laurence Sterne
10. Self-respect permeates every aspect of your life. ~Joe Clark

Without self-respect there can be no genuine success. Success won at the cost of self-respect is not success for what shall it profit a man if he gains the whole world and loses his own self- respect

~ Forbes

Even worse - and beyond self-respect:
And what do you benefit if you gain the whole world but lose your own soul? Is anything worth more than your soul?

~ Jesus (Matt 16:26 - NLT)
