Hopkins Study shows you a new approach to learning and mastery
This mirrors some of the ideas written on how learning by deliberate practice as outlined in the book Talent is Overrated by Geoff Colvin.
Use this approach to get yourself to the next level. I suggest reading Colvin's book if you want to become an expert in any field and to make yourself an exceptional performer. If you choose to accomplish this on the tennis court then you have an advantage of a large talent pool of coaches and teaching knowledge to get you there as well. You have to do your part though.
