I agree that 'starting a company' is the first step, but I disagree that inertia takes over.
If that is what the author is relying on, I'd say he is more likely jumping out of a plane without a parachute, a landing zone, or any idea how he is going to get back to civilization.
Inertia in business only has an effect if you are continually putting in efforts and those efforts sometimes multiply to create inertia. But like riding a bike, if you stop pedaling, you'll coast for a bit before it all comes to a hault.
Great analogy with the bike - continued pedaling is absolutely key. I think the skydiving analogy is trying to capture that feeling you have when you're teetering on the edge of the plane that makes a lot of people turn back or never jump.
After the jump though - the parachute and landing zone become critical.
