I can't help but feel like our modern society has sadly become the opposite of what this quote is talking about. Rather than slow and accepting, we're all about doing things fast and efficiently and betterment at all costs. The growth mindset, get up and grind, etc etc. Can't you practice faster? Learn faster? Put in more time? Even the most a human can reasonably do is never enough nowadays. High achievement is the new table stakes. IMO it's time for our society to take a hike and allow us to return to the spirit of the quote you've shared.
