A Habit is when it takes you less brain to do it, because it has become automatic.

What we call “muscle memory” is actually Kahneman1 mind, he calls it “System 1”, but that’s a useless label, without context, and its function is imprint->reaction.

“Thinking Fast & Slow”, the most profoundly-important book in the whole world, right now ( because the ideologies/prejudices are trying to displace Kahneman2 mind, considered-reasoning, from all authority in our world, and the more stressed everybody gets, the more success they have in doing-so ) is on the difference between the 2 systems.

Imprint->reaction mind can be quite useful, in one’s mental-economy, as it makes things happen on autopilot, but … if one tolerates its systematic substituting of its convenient reactions, for the actually required actions, … it can become strategically dangerous…
