We have shown how motivation, willpower and control get significantly confused in fitness. How then can we control the outcome of our efforts?

The only actual and reliable “control” you have is the ability to make educated decisions. As daily happenings provoke varied feelings you can allow it to just wash over you. Your responsibility is simply to sort through it and learn to become picky with your reactions.
