For me, every once in a while bits of a story DEMAND to be told so I sit down and write them if I can (and sweat a little and hope to remember them when I have a chance to write if I can't... and then forget them 90% of the time). So the motivation has never been an issue for me, just finding the opportunity... UNLESS I have a deadline. If I have a deadline (self-imposed or external), that is often the motivation I need to write (well, 7 times out of ten, the other three it is why I feel guilty for not writing...)
From each department by their ability, and to each department by its need. One department doesn't charge another department for services. The Janitorial department doesn't bill the HR department for emptying trashcans. Sales doesn't get a bill from HR for hiring new sales reps.
Just a technicality - you're describing core Communism but using the term Socialism. Core Communism requires society to break down into united Communes, each essentially its own country but all working together to better the whole, and believes this is a natural survival trait, and that "government" needs to be essentially weak to maintain distribution and keep the communes talking to each other. The belief is that the State is God, Father and Mother and all work together to support it because it is right and good to do so.
Socialism realizes this is not a natural trait but a learned one and that to make it happen you need a strong central authority. The idea is that God is optional, the State is its own thing and all work together to support it because This Is The Law, for good or for ill.
Most corporations are. indeed, Socialist, with either a single CEO or board of directors running things and passing the Rules down from On High. Most families are more Communist, with some degree of democratic principles, with "adults" present to step in if things get out of line, but mostly there as a figurehead.
