'Mastery" by Robert Greene 4/5
I grabbed it, tempted to learn if I can be a master. The book reveals, through sampled biographies, a framework leading to mastery. The study is backed up with dozens of examples and only a few redundancies appeared, mostly when repeating information that had been previously covered, which wasn’t a big deal. After the last page I had not mastered anything but I see that one can and how it is possible. There is much more to it than the alignment of the stars. I give this vast effort on understanding how mastery materialises four stars.
