I sometimes see grind culture and motivational posters on my feeds sometimes and they irritate me quite a bit. They also have the most generic advice like: get up at 4am, morning workout, cold showers, listen to podcasts, check emails, etc.
My dad runs a fairly sucessful small business and he works from 11am to 6pm and he never gets up early or does any of that morning routine stuff. Sure he will work out every other day when he gets back home. Even if I had all the money I need I will never get up that early and I did that for years and it sucked.
