A solid book explaining why some people are much more sensitive than others and how to deal with it if you are one of those people. The descriptions of hypersensitivity definitely resonate with my own experiences. I wish it went into much more detail on how to deal with it in real life. Aron tries to cover too many topics-- childhood experiences, work, relationships, etc.-- that makes the book seem a bit unfocused and the information/advice too general to be truly helpful in any practical way.
