[personaldev] The biochemical underpinnings of willpower, and how we can increase it

There's now a substantial body of work on willpower that shows it is governed by a distinct biochemical pathway.

Some really interesting discoveries:
- Willpower is a limited resource.  If you expend it on one activity (eg putting up with a loud noise) it will be weaker when you need it for another activity (eg not getting mad when someone yells at you).  Thus it';s worth choosing what to focus your willpower on wisely.
- Willpower can be increased with strength training, just like a muscle.
- Low blood sugar decreases willpower.  (I used to tell high school teachers that eating in class helped me stay focused on the lecture.  Now I finally have evidence of this)
- Heart Rate Variability (HRV) is higher during high-willpower tasks.  This is REALLY interesting.  It's not mentioned in the article, but I know that high HRV can be induced by slow-breathing techniques used in meditation.  Biofeedback systems (eg the StressEraser and Journey To Wild Divine) train people to increase HRV.
