I said "effort" rather than "work," because it's fun* for me (though would be work for many others), is like completing crossword puzzles is for puzzle fanciers and mastering a videogame is for someone into videogames.

*The word "fun" may miss some of the nuances: sometimes the endeavor is compulsive, often it doesn't bring fast gratification, sometimes it's like crossing the desert. In any event, the nature of the fun/effort/work is testing ideas, other people's and one's own, and that's the effort that musicwrite people generally don't know how to make. More crucially, it's an effort that the musicwrite community doesn't know how to make.
