This. Most people by definition are not the very best. Not everyone is a Gary Vaynerchuck.
Most mediocre people we would think suck. Really look at the 50 percentile. Ever interview people with long careers, making decent/good pay, at well known companies, and wonder how in the world they even have a job? That is a an extreme example, but most people treat it like a job, something to get done, provide for themselves and family. That's okay, but they're not that dedicated in being the very best.
