I've been down to the burnout road once about a decade ago and almost a second time a couple of years ago, after which I teetered on the edge a lot until I reached the current phase of apathetic disinterest. Now I just drag myself from one (work)day to another.
Dunno if your situation is the same but I tend to get a huge bursts of energy when my focus switches to some new thing... and then I burn up all that energy in a flash and end up feeling guilty about failing to keep up with the pace.
What I guess I'm trying to say is... take your time and don't push yourself if you feel like you can't hit the update goals you set for yourself.
Anyhow. You know yourself best so take this advice with a grain of salt...
