I think this is poor and dangerous advice for anyone who wants to get ahead in life. If you are happy to coast by and not achieve much in life, sure, don’t work hard. But if you want to be one of the few who either rise to the top in your field or to create value in the world, then don’t feel bad about wanting to work hard. People generally learn by doing and those who do a lot learn a lot. Of course, don’t prioritize it over things that are important to you (physical health, family etc) but don’t feel it’s wrong to prioritize it above stuff isn’t important to you (eg Netflix and YouTube shorts).
