I’m a third of the way through, but I hope to finish. It’s poorly written & very repetitive. The first 3 chapters could have been one summary. Several times I had to re-read something a couple of times to decipher the point in the muddled train of thought. Wrong words, incorrect grammar & sentence structure... & repetitive. Did I mention that?
I thought it was amusing that the author, while describing the study method, emphasizes that reading the entire book you’re studying is completely unnecessary because whatever book you’re studying gives a lot of unneeded information. You don’t say.
I will persevere though, because I’m intrigued by the mind mapping concept.
