And, WC, if you're nervous, that's fine. There's always going to be some high pressure deal or something that will set the bar higher. Your targets are always going to get bigger. If they aren't, I'd suggest looking for a new job because the company isn't going anywhere.
Besides, intrinsic fear is a good motivator. Not unhealthy fear promoted by bad managers, but fear of failing and not doing as well as you'd like.
