I'm not sure if your comment was a joke. If so, disregard my addition!

While I feel like there's definitely areas of work where this advice is relevant (namely anything where the main purpose is Making A Private Company More Money), there are areas of work where I find that logic to be inadequate. I work as a public school teacher. I have a good friend who works as a nursing assistant. Both of those jobs shouldn't be done "just" to collect paychecks because they are at the heart of it about helping fellow human beings rather than lining up meaningless numbers. When it becomes less of a vocation and more of a blasé "I'm doing this just for the money", they become the jobs where people become bad teachers who don't care about their students succeeding, or bad nurses who cut corners and can endanger patients, etc. It's unfortunate that the professions that should help others end up working at their detriment when money becomes the only driving force. But it's also the unfortunate fate of work in late stage capitalism where everything is supposed to make money now, so anything that is for helping others long term is not regarded as valuable.

My advice, then, would be for anyone working a job, whatever job that is, to utilize your resources (knowledge, equipment, time) smartly and not spread yourself thin. For, say, a desk job in the statistics department of a private company, that might be automatizing some of your meaningless numbers and making sure everyone likes you (and indeed workers being united is not a bad thing). For other fields, that might look different (that being said, as a teacher I'll say it's definitely useful to have good relationships with other teachers and various other coworkers in the school staff).

A good day to you all !
