Super easy to get motivated to work on my own projects every Friday: I look back at how many and how difficult the things I worked on during the week. I take how much I got paid and divide it by the sum of (numProjects * difficulty(1 to 4)). If I spent anywhere near that number on just coffee this week, well then Friday afternoon goes towards working on my own projects (yeah Friday morning- still have a lot of work to do and coffee to drink.)
