This chapter by itself, i feel like epitomizes some of his insecurity. If you are the inventor of a mind mapthis chapter is included to show your superiority over everyone else's attempt at trying to think visually. And if you follow that, even his own sophoer wouldn't qualify this. So this reminds me of a scarcity mine set. Sometimes they feel like the minute that some one buys something from your competitor, youdin't do good enough job explaining why youare better.
