You don’t have to start fake clubs, take trips, volunteer, collect awards, or whatever else if you don’t want to though. Claims that some particular assortment of these is necessary an invention by parents/whoever who can’t conceive of time spent and choices made for reasons other than winning some game.
Activities like music/debate/programming/sport contests, tutoring younger kids, performing science experiments, hacking on computers, getting short stories published, working a part-time job, working for a political campaign, or whatever else have some intrinsic value/interest and are not just meaningless busywork for many (most?) of their participants.
In my experience the kids who pick one or two things they find personally interesting and pursue those out of real excitement end up significantly more successful in the admissions "game" than the kids who spend every waking moment trying to play it as a game per se. While also having a better time. And this is not because they are any inherently smarter or more motivated or whatever.
Rayiner almost always comes across to me as a cynic whose main goal is running up his family’s score in the money-earning game and who looks down on anyone with humanistic goals as merely an unsuccessful fellow cynic. Maybe that’s unfair, but that’s my persistent impression comment after comment, year after year. YMMV.
