Discipline can be awkward. Yesterday for example. The plan was to work straight through the day & night on optimising a couple of features for the AN Guide (geek: really couldn't justify loading 250K javascript on every New Thread page just on the occasional off chance it might be needed...).
It wasn't a big "pressure cooker" working day, the self set deadline of "before sleep" was vague enough to allow for plenty of pizza & half life zombie killing breaks, maybe even check New Posts every hour or so to keep the brain from stagnating. And yes, gosh darn it, friends could visit for a little while on the understanding I'd continue to work.
That's the plan explained. "Gatecrash Woolies' for a party" means that the next morning hosts an empty case of cider, full ash tray, red wine stains on the bed and a friend in hospital. The javascript works though. I think...
