“The chains of habit are too light to be felt until they are too heavy to be broken.”
Routines are extraordinarily powerful forces in your life. When you follow a process consistently, you learn to execute it on autopilot. There’s no thinking questioning or wondering “What to do?” You just shut up and do it.
That's why bad habits are so destructive. If you repeat a behavior enough times in a row, it becomes a habit. And then it's really hard to break. It is important to halt bad behaviors before they become habits. It's the best and easy way to avoid some major problems and pitfalls in the future.
