From the guy who build a homebrew CPU from scratch:
Although this site gets few visitors, I have on occasion gotten the comment that: (1) I have way too much time on my hands & (2) I must be single. Well, wrong on both counts! Married – 3 kids & two dogs, and not nearly enough time. I manage to make progress on the project by putting in the odd hour here and there and treating it as the multi-year effort that it is. It also helps that as far as my wife knows, I’m actually doing paying work on the laptop and not just screwing around with my hobby projects :-). (continued on the site’s home page, just scroll down)
