Making changes in my habits, especially exercise and eating, requires using my will power. Today I found out where my will power is located - in my ventral medial prefrontal cortex and my dorsolateral prefrontal cortex. Oh, well of course. ummm, where is that?
This image at Wikipedia puts them both near the front of the brain. Being able to picture where my will power is kept does not help me to access it when I need more of it. For tips on how to do that, see these ideas published at Livestrong.
