Education: the path from cocky ignorance to miserable uncertainty. - Mark Twain
Class is an aura of confidence that is being sure without being cocky. Class has nothing to do with money. Class never runs scared. It is self-discipline and self-knowledge. It's the sure-footedness that comes with having proved you can meet life. - Ann Landers
Most insensible, corrupt, cheap, disrespectful young girls run after bad, rude, cocky, nonsensical boys, but a mature, educated, thoughtful, virtuos lady opts for a wise, well breed, experienced, humble, modest gentleman. - Michael Bassey Johnson
If you have the choice between humble and cocky, go with cocky. There's always time to be humble later, once you've been proven horrendously, irrevocably wrong. - Kinky Friedman
Nothing amuses people more than a cocky guy who starts losing. - Criss Jami
Confidence, is like a belt worn around the waist. Wear it too tight, you come off cocky and arrogant, wear it too loose, you come off timid and a walk over, but wear it fit and snug, it will uphold you in every step of the way. - Anthony Liccione
