What gets you out to the garage to work on your machine? What motivates you to want to spend more money and spend hours out in the garage thrashing on your ride to get it a bit quicker than it was?

I was listening to the podcast of SO today and that got me wanting to get out and start working on my stuff, then I realized it's a 20 min drive to the shop, then I have to walk past all the work I have to do there, and I just give up. I need to stay motivated to finish my turbo coyote and get it at the track this year.
So, share, what gets you going?
