I've been there. Several times, actually. A few things that may apply to you...

* If you started 4 projects you obviously still have desire. Don't push yourself. Maybe just keep tabs on interesting things, or maybe poke around in a new language, or look into anything you're curious about without any commitments.

* Even a really good day job in programming can take away energy for side/personal projects. In fact, the better the job the less mental energy I have left for my own stuff. I wish it were different, but I've mostly come to accept it.

* The world is full of small things that you can do to make your life better. When you find something repetitive in your life, consider writing something to take care of it. Doing small things to keep busy and improve your life is a nice way to get the joy back. Keep it small and simple to start, so you're not face with a big project you don't have the enthusiasm to complete. Do things you can finish quickly.

Good luck!
