Willpower

Willpower is just a label we use to explain our choices after we make them. In reality, you do not have a magical tank of mental strength to fight off temptation. Instead, your mind is just a battleground for competing desires. When you eat a slice of chocolate cake instead of sticking to your diet, your willpower did not fail. You simply wanted the instant pleasure more than you wanted long-term health at that exact second. Stop feeling guilty about it. The real solution is not to summon a fake force that does not exist. You just need to consciously change what you actually want.
