if your headed into this field and need research fine this is for you. if you want any actual knowledge and your not a PHD then run. this has got to be the most dull book I’ve ever heard. the voice is good but the story just runs on and on about absolutely nothing. I dont think I’ve ever said this about an audiobook.im sure the author is great and all but this is more a textbook. this is trash. sounds like chat gpt wrote it.
