North star metric

The idea is to pick one figure you check first and use to settle arguments. Product teams do it so everyone stops optimising a different dashboard. It transfers to a channel: one creator steers by returning viewers, another by hours watched, another by email signups from the description. Choosing well matters more than the discipline of having one. Anything easy to inflate will get inflated, and a number that climbs while the work gets worse is worse than having no number at all. Pick something hard to game that you can actually move this month.
