Well, I hate cleaning and I have issues with clutter. I wind up with piles of stuff on the desk, dining room table, coffee table, dresser, etc. Then when I need to clean it all up (e.g., because I'm having visitors) I'm overwhelmed by how much needs to be done.
So I've found one part of the solution is to do a little at a time -- spend five minutes cleaning one spot and do that every day. Often once I get started I'll wind up spending 10-15 minutes cleaning up two or three spots. And over the course of a week or so, everything winds up neat. (BTW the other part of the solution is to go to The Container Store and buy things that make it easier to put things away faster so the clutter doesn't build up so much in the first place. ;-))
So, maybe you could apply a similar principle to the bike -- plan to assemble/attach one component. When you're finished with that, decide what the next thing to attach/assemble will be and plan to do that tomorrow. It will take more days to finish but the time requirement each day will be relatively small. I think the best way to pull this off would be to have a dedicated work area where you can leave the frame and other stuff in the workstand all the time so you don't have to set up/break down your work area every time you want to do something.
