We all run patterns or habits.
Often they're useful - getting up at the right time, eating meals, that kind of thing.
But sometimes they're less useful - biting your nails, procrastinating, never quite keeping all your promises.

Any and all of those patterns can be interrupted if you want to.
Sometimes as simply as asking the question "why" enough times until you get to the root cause.
Sometimes by going off at a tangent and seeing where it leads.
Give it a try on anything that's holding you back or any pattern you're running but would rather not be running.
