Have you ever gotten home at the end of the day, and found yourself struggling with the willpower to either do or NOT do that thing that you keep meaning to do? Or not do? You will go to the gym after work. You will not snack on cookies at the end of the night. And when you don't stick to those goals, you feel shame and frustration that you just can't. But the reality is, willpower is finite - and the better you understand willpower, the more likely you'll be able to use it to help you get where you want to go.
