I feel the same way. ;-)

Most of the projects I work on in my free time I start because I want to learn about something (new language, new UI framework, whatever), and once I feel I have achieved that, my motivation drops dramatically.

Also, not having to deal with deadlines, strange and ever-shifting requirements, or angry users is part of the fun. Walking away from a half-finished program is not something I could get away with at work, so it is kind of a relief to be able to do that sometimes.
