Doing it the way you’ve been doing, that’s when you’re on autopilot. You don’t know what you’re doing. You have mastered a way of thinking and a way of doing. It’s a good thing if your goal is to complete something the most efficient way.
But it’s bad if you intend to stay mentally fresh because your mental muscles stopped developing. It’s as if you’re doing the same workout every other day and you wonder why your body doesn’t react anymore. I even made the experience that my toothpaste stopped working after a while. My teeth no longer accepted its ingredients. So I had to change the toothpaste.
Treat your muscle memory with new impulses. Your mind (and your body) want something new every now and then.
If you do something out of rote behavior, then ask yourself: Is this REALLY the best way to do it?
Do it with the right intentions and do the right thing. Doing the right thing is always the right thing.
