A body at rest will remain at rest. A body in motion will continue in motion unless acted upon by an unbalanced force.
Holy apple-boy! Was Isaac Newton a physicist or a philosopher?
See, it's like this...I'm a body at rest. And I tend to remain at rest. Sometimes it seems my entire life has been ruled by the Law of Inertia. Resistance to change.
Maybe you can empathize. If you're like me, you've probably missed some opportunities because of inertia.
On the other hand, you may have also missed some catastrophes because of inertia.
