Wow. This is such heinous and poisonous advice I actually considered flagging this post.
Learning how to focus and building a high quality work ethic is important, but your advice is horrid. Following it is likely to lead a person to becoming a burnt out husk of a human being by the time they are 40, if not sooner.
Actually, it turns out that it's neither heinous nor poisonous. You seem to be having an allergic reaction to the contrast between advice about how the actual world functions and how actual productive people function in it, and the flowery advice given in the article.
Basically, each of the 5 points I listed comes down to, "Momma said there'd be days like this, days like this Momma said!"
I guess, at this point, I'd be curious about what, in particular you found "heinous", "poisonous", "horrid", or likely to lead to one becoming a "burnt out husk of a human being" before the remarkably specific age of 40. However, I suspect that you'll find you've imported a bit of your own baggage into your explication.
I found your post to be a bit unproductive (despite legitimate content) because it was so deeply ridden with spite and disdain; too much focus on name-calling! Without the smug superiority complex and palpable hatred for a certain group of people you clearly consider beneath you, it would've been a bit easier to engage with.
Even a bit of humility about whether your personal vantage point and opinions are accurate pictures of the entire "real world" would help...
