Jonah Lehrer summarizes the findings of a new study on willpower:
[This study helps] us map out the individual differences that make it slightly easier for some people to engage in hard labor. These diligent souls seem to get a bit more pleasure from the possibility of reward, but they also seem less sensitive to their inner complainer, that disruptive voice reminding them that minesweeper is more fun than editing, or that the ballgame on television is much more entertaining than their homework. At any given moment, there is a tug of war unfolding in our head, determining whether or not we’re willing to put in the effort. This sentence only exists because, for a few minutes at least, I was able to win the war.
