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

I like you arguments and the way you positioned this. Thank you!

I am still not sure if there is such thing as a 5.000 or 10.000 hour rule to be a specialist. What if I learn for 5.000 the wrong skill, or not the right way? It essentially makes me a specialist in knowing the wrong stuff… Apply this to learning a practical skill like learning to play the piano, or how to hit a golf ball straight. I put in all the effort, and in the end I am still not able to play like a pro. What I am saying is that learning something and putting in the effort is not the only solution. You need to learn the right thing…and this is where your arguments come in! How the heck do I know what the right thing is if it changes so fast? Will I ever be in a position to know something so well that you can call me a 'specialist'? Maybe not… 
We are heading for interesting times. Knowledge will be more a commodity than ever before, accessible anytime, anywhere, personalised and ever changing. And with technology becoming more and more ubiquitous, we are in for an interesting future!
