Habits are a choice, until they aren't. We can choose which habits we adopt when we repeat them. Over and over. Do you want the healthy habit of exercising every day? You know what comes next: exercise every day.
As James Clear points out in his useful book Atomic Habits, the best support to a good habit is to do it every day without fail. You might not always do the habit completely and seldom will you do it perfectly but zero repetitions is not acceptable. If your goal is to do 100 push-ups a day and you must fail today, you fail by doing SOME push-ups (maybe 50, maybe 99) but you certainly don't do ZERO push-ups.
Leaders must form healthy habits and do them every day in order for our team members to pay attention and adapt healthy habits of their own. Behavior is contagious, even exemplary behavior.
Show what you want. Do it.
