Ask HN: Finding time to work on personal projects

How do you find time to work on your personal projects(While working a 40+ hour work week)?

In my case I am currently interning in a IT related job, so I am staring at a computer screen for 8+ hours a day. By the time I get home the last thing I want to do is sit down and stare into another computer screen. The only real time I get to work on personal projects in late at night on weekdays for about an hour or two. At this rate I will never be able to complete anything in a reasonable amount of time. I travel/work a lot on the weekends(prime personal project time), so I can only really work on it then.
