It’s not just about writing down sc rules, we need to follow them and from personal experience when it comes to outlook of the world and habits in general our brain is like a leaky bucket, it requires constant refill, and without refill of your own sc it will fill up with everything else that ends up being pushed on you.
As there is a never ending stream of information and events that is flowing at you, and we very much risk filling up the bucket with such flow unless we ourselves choose to refill it with our own sc. (See Tony-Robbins discuss current-events as a flow).
Think of sc as your programming but the programming fades away. In some respect to properly brain wash yourself you need to continusly brainwash yourself. Think how successful religions do it, Christinanity doesn’t just do an intense one month dive into the Bible and calls it a day, they meet once a week, again and again to refill the leaky bucket of human brain.
The leaky bucket is not a terrible thing either it allows us to adapt, to changing circumstances, to allow reconfiguration of neurons, but it does very much create the use it or loose it with skills and thought patterns.
