“naturally gravitate toward the path of least resistance. By using this principle, it’s easy to see that when starting a new habit, the best way to do so is to figure out how to expend the least amount of energy possible. If you want to begin training to do pull-ups, you don’t set a starting goal of 100 pull-ups a day. You start with one, and as the habit builds, you add more until you reach 100. Because of the way our brains work, this approach is most effective. Another way to make new habits easy is to reduce the amount of friction between yourself and the new habit. Many people have high goals when trying to establish a new habit, but they find themselves unable to sustain it over time. They feel that the habit is too time-consuming, expensive, or difficult. These are all sources of friction. The more of these common problems you can erase before beginning your new behavior, the more likely it is to become automatic.”
