I've said it before, and I'll say it as many times as is needed: you are dealing with a shitty situation, and doing a bloody good job of it, all things considered. You have identified an issue (task burnout), and you deal with it correctly, by leaving that suddenly unpleasant task and working on something else, so you remain as fresh as possible.
That said, I have to admit that hearing of a release for MNF2 in the next few months (December counts, right?) has me stoked. MNF1 was our first introduction to this little world, and quite apart from the next generation, I'm really really keen to discover more about how and why the family seem to have unusual qualities.
