A lovely artist friend of mine told me this quote recently, and it's so useful.
"Habit is a thick rope."
Think of a "bad" habit you have, one you want to get rid of.
Strong, persistent habits, probably like the one you chose, are like a tug-o-war rope. Each fiber in the rope is a specific time you played out your habit. Your habit started off a thin jumble of fibers, and is now a tightly twisted, thick rope. It took time and work to get it that thick, so it'll take time and effort to unravel.
In the case of habits, they're unraveled by
- Softening your anxiety/resistance/resentment towards it
- Shining awareness on it: when, where, how the habit surfaces
- Enacting the habit you do want instead
For y'all who are bored of the rope metaphor: Habits are super-strong neural pathways, etched over time. To weaken it you must stop, shine awareness, and work on strengthening the baby neural pathway that'll make your life better.
