(1) Abundance mindset - it is not that the world has enough for everyone. The world has enough for everything you want. Abundance is not a social responsibility.
(2) Self-awareness is quite hard, and most people don't know how to be self-aware, and worse, go on about thinking they are, but they aren't.
(3) No one will pay you what you are worth. They will pay you what they think you are worth. It's up to the individual to go get what they are worth.
If you depend on self-improvement books for growth, its a limited world view. A realist meeting a self-advocate is the only kind that will succeed despite the waxing and waning economic conditions.
Overall, an interesting and different read.
