I suddenly started thinking, what qualities should a KOL have? Arthur Hayes once said: The best position for you is the one that lets you sleep well every night. I think there’s a similar saying that applies to KOLs: If you can still sleep well even when a bunch of people are criticizing you, then you’re definitely cut out to be a KOL. This saying also applies to community managers, CMOs, founders, and anyone who needs to run social media.
