Yup, never look at a large job of any sort in it's totality, except to decide on where to start. Then, "keep it simple stupid", and assign yourself one really small project at a time, something you can complete in one day. And make sure to keep your project on the front burner, don't let your projects languish for weeks/months/years, you'll likely never finish. Personally, I like to tackle the hardest jobs first and finish with the easy jobs. That way, the project get's easier and easier as you go along. You're at that hard job stage now. Conquer this one and you've earned yourself a victory beer. Conquer the next hardest job and you've earned another beer. By the time you're done and your car is ready to drive you'll have drank cases and cases of beer, you'll be an alcoholic, and you'll be able to get a DUI ticket on your very first drive. Good times!
