The Math Behind The 5-Hour Rule: Why You Need To Learn 1 Hour Per Day Just To Stay Relevant
Michael Simmons

Thank you for the wake-up call, though it’s not much needed in my case. However, I only half agree, particularly on the part that people are investing more and more time into learning. I think that, in the real world, there is a tipping point at which learning (at least in the narrow sense of book kmowledge, courses etc.) doesn’t contribute much to performance because people start missing out in experiences to use their knowledge in real-world projects and situations. This remark is partly self-critical: it’s never as hard to stay ahead in the real world than during a PhD and/or postdoc. You absorb a lot, do some research, but then? Also, not everyone has the same capacity for learning, so even if more effort goes in, it need not yield proportionately more outcome.

My 2 cents!
