Indeed. The central point of the book is really the importance of human empathy. If you want to influence people, you have to consider their needs and wants rather that just being self-absorbed and entitled all the time.
True, but it's hard to force oneself to care about other people, to be honest. Many are naturally self-centered, and it's not easy to trick/convert one's mind into not being self-centered. There are some tips like finding a common interest, but not enough. The book has gaps in that aspect.
