The fact of the matter is that there will be nothing learned from any challenge in which we don't try our hardest. Growth comes at the point of resistance.

Learning happens where something pushes back. If a task is easy, or if we only half-engage with a hard one, we get little out of it, because nothing in us has to change. Waitzkin's point is that effort and resistance are the raw material of improvement, and that the struggle itself is where the lesson lives. Holding back protects us from failing, but it also hides what we would have discovered about our limits.
