If you look up the etymology of the word “habit,” it means to hold, consider or have in mind.
That’s right: Habits are thought!
No surprises there, eh? 😆
Given the capricious, ever-evolving nature of thought, it also explains why habits—these behaviours we see, that lie downstream of the beliefs holding them in place—tend to come and go.
They’re held in mind. And then they’re not.
