Self-promotional, slow, and shallow can still be true: "5-Hour Rule: If you're not spending 5 hours per week learning, you're being irresponsible" has many nuggets of truth in its chatty expansion of a simple, supremely valuable theme:

Among the best bits in this Michael Simmons 2017 essay are his observations:

• "... the world's smartest and busiest people find one hour a day for deliberate learning ..." (in a recap of the author's own 2016 article "Bill Gates, Warren Buffett And Oprah All Use The 5-Hour Rule")
• The more you give away knowledge, the more you:
  • Remember it
  • Understand it
  • Connect it to other ideas in your head
  • Build your identity as a rôle model for that knowledge
• "Master the skill of learning how to learn. Doing so exponentially increases the value of every hour we devote to learning (our learning rate). Our learning rate determines how quickly our knowledge compounds over time. ..."

... all good metacognitive observations — despite an overly long, distractingly disorganized presentation (with fake-filler inspirational quotes).
