Essentially, you create youtube videos where the challenge is to learn a skill or something in 24hrs. You stay up for the whole 24 hours and film yourself as you make progress (or don’t), and then clickbait the shit out of it.
Could benefit from viewer suggestions, but some things like learning a language definitely won’t work. Also, practical skills like archery or whatever may be better than mental skills like calculus or some bullshit. Unless you’re learning your times tables for the first time, nobody gives a shit.
