When you press the start button on your life system (at birth), you create inertia with the choices you make. Every choice. You create brain patterns whose job is to keep that system in motion. This is why so much of therapy goes back to childhood, because it’s important to look at when your psychological inertia was formed. Without any outside force acting on your system, it will stay the same. But with too many different forces acting on your system, it will push back on all of them, to remain in motion.
