Good One on Attention and Concentration

Napoleon Hill said the following words about attention:

“Controlled attention is the act of coordinating all the faculties of the mind and directing their combined power to a given end. It is an act, which can be achieved only by the strictest sort of self-discipline.”

“Learn to fix your attention on a given subject, at will, for whatever length of time you choose. You will have learned the secret to power and plenty! This is concentration.”

“Keep your mind on the things you want and off the things you don’t want!”
