Literature boils with the madcap careers of writers brought to the edge by the demands of living on their nerves wringing out their memories and their nightmares to extract meaning truth beauty.
I have a crazy amount of different jobs so the way I manage that is to not do more than one at a time. It's like old computers that had small memory chips they would do something called swapping where they would fill the memory with one task do it and get it out.
