Newton's first law.
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This tendency to resist changes in a state of motion is inertia.
Change requires an external force.
Overcoming resistance requires an external force.
The status quo will remain the status quo unless we apply an intentional force.
Things don't get better on their own.
They get better through intentional action.
