Mastery requires practice. But the more you practice something, the more boring and routine it becomes. Once the beginner gains have been made and we learn what to expect, our interest starts to fade. Sometimes it happens even faster than that. All you have to do is hit the gym a few days in a row or publish a couple of blog posts on time and letting one day slip doesn’t feel like much. Things are going well. It’s easy to rationalize taking a day off because you’re in a good place. The greatest threat to success is not failure but boredom. We get bored with habits because they stop delighting us. The outcome becomes expected. And as our habits become ordinary, we start derailing our progress to seek novelty. Perhaps this is why we get caught up in a never-ending cycle, jumping from one workout to the next, one diet to the next, one business idea to the next. As soon as we experience the slightest dip in motivation, we begin seeking a new strategy—even if the old one was still working. As Machiavelli noted, “Men desire novelty to such an extent that those who are doing well wish for a change as much as those who are doing badly.”
