Scale the wall within
yourself & the rest will crumble.
"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."
