Obstacles are necessary for success because in selling, as in all careers of importance, victory comes only after many struggles and countless defeats. Yet each struggle, each defeat, sharpens your skills and strengths, your courage and your endurance, your ability and your confidence and thus each obstacle is a comrade-in-arms forcing you to become better... or quit. Each rebuff is an opportunity to move forward; turn away from them, avoid them, and you throw away your future.
Og MandinoEvery memorable act in the history of the world is a triumph of enthusiasm. Nothing great was ever achieved without it because it gives any challenge or any occupation, no mater how frightening or difficult, a new meaning. Without enthusiasm you are doomed to a life of mediocrity but with it you can accomplish miracles
Og MandinoI will persist until I succeed. I know that small attempts, repeated, will complete any undertaking.
