The man of business knows that only by years of patient, unremitting attention to affairs can he earn his reward, which is the result, not of chance, but of well-devised means for the attainment of ends.
Andrew CarnegiePeople who are unable to motivate themselves must be content with mediocrity, no matter how impressive their other talents.
Andrew CarnegieI believe the true road to preeminent success in any line is to make yourself master in that line. I have no faith in the policy of scattering one's resources, and in my experience I have rarely if ever met a man who achieved preeminence in money making.. certainly never one in manufacturing.. who was interested in many concerns.
