Inertia is a property of matter.

Often times I observe how life has it's own momentum. When a few key things start getting good, more good things follow and vice versa. Feast or famine. The tricky part is finding out what those key things are and how to jump start them in the right direction. But once that's done, the rest should follow.

Momentum and inertia are different things, as momentum is not a property of matter.
