The compound interests of learning
When you learn productivity tips, there is hope for long term ROI on the time you invest in learning. If you know the power of coumpound interests, then you can infer that the soonest you know something, the more value it generates over time.
Investing 1 hour today to learn something that will make you win 12 seconds per working day saves you 1 minute per week so almost an hour per year for the rest of your career ! Well, I know what you mean, 1 hour saved per year won't change your life. But guess what happens if you invest one hour per week to perfect your workflow ? You literally save years, I am not kidding, do the math !
Let's compare someone that doesn't invest in perfecting their workflow and someone who does. Let's say both are given a 40-years-long task given their current skills (working 7 hours per day, 5 days per week, 47 weeks per year (5 weeks off per year)). The one that doesn't perfect its workflow will take 40 years to make it. The other invests 1 hour per week in learning, and for each hour invested, he wins 12 seconds per day over his workmate. It will take him 9.5 years less than his non-learning workmate to do just as much.
A one hour learning session for saving only 12 seconds spared each following days doesn't seem much, but it could make you retire 10 years earlier. That's why one must learn.
