"Another reason to avoid stopping a good habit is that, sadly, starting again is often far harder than starting the first time. It's natural to think, "Oh, I did this before, it will be easy to do it again," but often it's much harder to start again. True, taking that first step the first time around can be hard, but there's also a special energy and optimism to launching a new habit. When I've tried to summon up the same energy for restarting a lapsed habit, it hasn't worked very well. The novelty has worn off, I've remembered all the reasons I struggle with that habit, and it's discouraging to feel myself backsliding."
