When I was planning my 7DRL I realized that in fact I need some time off from roguelikes and programming. I think a month will be fine. I also try not to visit roguetemple's forum or any other roguelike-related place.
I'm not going to sit still, there are many things to do which don't get as much effort as I want. Well to be honest I'm in some kind of crisis... maybe it's this age issue and... stuff.
The big question is can I stay month off?
