James Clear, the author of
Atomic Habits and a leading authority on the subject, is a
firm believer in habit tracking. Building a habit is a long-distance race, so you need an overview of your progress. When you're feeling out of steam, your tracker shows how much you've already accomplished and it will boost your motivation. And if you start falling off the wagon, you'll notice it immediately and get back on track before it's too late.
Last but not least,
tracking habits can be a fun and motivating task if you've found the right tool among the countless habit apps and bullet journal ideas!
