"If we use up our willpower resisting one temptation we will have less in reserve to resist the next. That’s a big deal because you don’t want to use up all of your willpower resisting a cupcake.."

That is true, but also you can't avoid this situations because if "willpower behave somehow like a muscle" you have to train it. It is hard to find a mix between training your willpower and not spending too much willpower on training and having nothing left.

I recommend everyone to read more about this topic, there are great books out there which explain how willpower works in your brain and body.

One little trick helps me a lot.. If you look at your stuffed garage say to yourself: what a beautiful pile of willpower training.

I think a wrong concept is being circulated around. Will power is not energy, and there isn't a 'bank' you are depleting. And there isn't a 'spending' will power. If you are hungry, just go eat something and get back to work. Working while running short on energy is one of the things where will power helps, and not the only thing.

There are plenty of people who are very healthy and fit, but can't push for a minute extra beyond their threshold of tolerance.

If you look at it that way, Will power almost has mystical effect surrounding your ability to do certain things when they seem impossible to people outside. Which is why not every one eating and living healthy is swimming the English channel, or writing the next operating system, or playing the football world cup finals, or some one in dire poverty rising their way by hard work.

These things can't be gained eating something or living a particular lifestyle.

The prefrontal cortex regulates the three challenges "I will not", "I will" and "I want". These three challenges cost energy everytime we make it.

That is what we call willpower. And almost everything you do needs willpower. Willpower doesn't only come in if you wan't to push further.

We require energy to do anything. Even to just merely exist.

But that isn't all there is to, is it?
