1. Asking willpower to do too much
A slew of scientific research shows the most important thing you can understand about willpower is that it’s a limited resource. That means, once you’ve used up your reserve of it, you’re pretty much done. In one such experiment, group A had to watch and focus on a boring video scene, while group B did not; then both groups had to circle each ‘e’ in a long piece of test. Group A, who had already used much of their willpower to watch the tedious video, gave up much faster.
Translation: If you’re trying to quit smoking and work out five days a week, that’s great—but don’t try and do it at the same time. Spread your objectives out over the year. And when possible, don’t leave your goals to the end of the day when you may have already depleted your cup of self-control.
