"inspiration comes from working on something, not from thinking about it" Not sure about that - the applications I'm most proud of actually came from extended periods where I was involved in maintaining an existing system, carefully thinking about how it could be improved, so when a chance came I could propose a new application with a well defined list of benefits. Note that by "extended period" I mean a couple of years!
