Just wait until you get to the point where you randomly think "I want to do something." and then go ahead with it. This is what I do at EoFF. I can be (relatively) idle for long periods and then suddenly get the urge to undertake a project and I do it until I lose the enthusiasm for it. Sometime something will jump-start your desire to be active again, sometimes it'll just come naturally. If it doesn't happen, so be it. But there is little point in trying to force it.
