I found this book very useful for me as a communicator. It's mostly about communication, influence, and a bit about design. I think you can apply most of the stuff in this book anywhere; it applies a design lens to good communication. It is a problem a lot of designers have, often thinking, "If only I had a seat at the table".
If I had to take just 1 takeaway, it's the nugget, start with "Yes". The "yes and..". It can be difficult, but I try to talk in these terms to people always now. Read the book, check out what I'm talking about. One of the best 'Design' books I've read in a long time.
