GM Automotivation, How to look forward to the occasional oneshot after GM-Burnout? Options

[MK Ultra]

Hey Chummers
As an SR-GM, i suffered burnout some years ago, but my regular groups resistence to other games and unwillingness to GM in my stead makes us play the occasional oneshot. Sometimes I am craving to run an SR game, but most of the time, I am indifferent at best. Add to that, that its usually fairly spontanious, so i have little preparation time and don´t get to see the PCs in advance usually. Once I see them, they do usualy fail to capture my imagination.

This is seldome a problem when I am running any other game, give an introduction to SR-noobs od get to just play a PC.

While I fail to have the motivation to prepair a full campaign -because those usually lead to nothing after a few sessions due to party disintegration- I would like to enjoy a game with my old buddies now and then.

So how can I enjoy it? Any tips appreciated.
