More of a discussion prompt than anything else today.
Everyone has bad days/weeks/months. However, just because you're feeling mentally fatigued, or depressed, or something similar doesn't mean you're going to cancel your game. Especially when it is some of the only wind down time that you have that week.
So, the question is: when you're totally not in the mood for doing the work needed to GM, how do you overcome it and get yourself in the mood?
For myself, I tend to use videogames to at least get my head into the idea of things. Depending on the game changes the videogame, but it is often a game that is very different from the game I'm running. (i.e. I'll do a few rounds of Mass Effect's multiplayer to get my head into place for L5R.) How about you?
