Momentum

What is this momentum I keep using as a metaphor? Rather, what is it for? Well, it obviously isn't a good thing...to me rather. To simplify what I mean, I'll compare my meaning to something more relatable. Here it goes:
I am like a runaway car of lies and bad luck, with no brakes ever installed or hills ahead to slow me down. I can only stop when I hit something, rather someone. I will finally become stationary, and be able to live peacefully with a firm stance rather than running nonstop. But there is a problem, I only become stationary when I have completed passing on my momentum. The momentum of lies and bad luck, some could even say failure. Well then, what's there to lose besides all the bad qualities I posses? Obviously you havn't considered my perspective, which I have come to understand as a wiser part of me. I've realized that my momentum could cause the happy and successful qualities of the person I hit to becomes lost, thus carrying my momentum of lies, bad luck, and failure. So what? I'm free then right? Well, not quite. Momentum is a game, it doesn't want a loss of "players", so some universal casualty will bring forth a new burdening momentum to me as I pass on my "old" one. This momentum has already struck me before it has even begun it's preparation for me. This new burden is called guilt. I pass on my momentum of lies and etc. to someone so I can stop, but then my mind races with the guilt of my selfish ways to lest it be anything but stationary.
I want none of it, but I have to live with one of it to save all of them. This may not be a defiance of momentum, but I've voluteered to play its game against its intentions... and the only way it can stop me is if it steps up in my runaway path, and let me pass on my momentum of lies, bad luck, failure, etc. and wisdom. Until then, I steer my runaway car away from everyone, dodging traffic set up by the game, until the game forces the stop... of me and the game itself.
