In this video, a man argues that willpower is like a muscle that everyone possesses but must be trained to become strong.

He explains that individuals with strong wills have systematically strengthened them by exercising them regularly with progressively more difficult decisions. He suggests that a cultivated will can break through any internal resistance, which he refers to as resistance from "the me" (or the ego).

A key point he makes is that as the will becomes stronger, the internal resistance ("the me") weakens, almost as if it learns that fighting back is pointless. For those who are not used to exercising self-discipline, this internal resistance will "throw a tantrum." His advice is to ignore this internal protest and follow through with the decision anyway. This practice, he states, cultivates a powerful, self-disciplined attitude, enabling a person to accomplish almost anything they set their mind to.
