Obstacles are necessary for success because in selling, as in all careers of importance, victory comes only after many struggles and countless defeats.
Og MandinoThe weakest living creature, by concentrating his powers on a single object, can accomplish good results while the strongest, by dispersing his effort over many chores, may fail to accomplish anything.
Og MandinoLet your actions always speak for you, but be forever on guard against the terrible traps of false pride and conceit that can halt your progress. The next time you are tempted to boast, just place your fist in a full pail of water, and when you remove it, the hole remaining will give you a correct measure of your importance.
