Self-help author and motivational speaker Anthony "Tony" Robbins has been a giant of the contemporary self-help field since the 1990s. His book "Awaken the Giant Within" published in 1992 advocates a strategy he calls concentration of power, or the harnessing all of a person's ability to accomplish their goals. Robbins urges readers to rid themselves of limiting thoughts and to elevate personal standards. We all, Robbins says, must believe ourselves to be capable of more.
