The author is taking the Taleb advice too literally and without enough nuance. One needs to calibrate the difficulty of the task. Ideally, one sets it so that it is in the region where it is just beyond the grasp of ones ability. The author seems to have dialed up the difficulty way too high considering the author's skill level. This is like trying to learn to play violin and going straight to Paganini... it is not an effective use of time. Just because Magnus Carlsen is using a computer to train does not mean a beginner should do the same.
