In law there is always another way
Format: Kindle
I finished this book having completed all but one course for my law degree. It is a goldmine of techniques and outlines the modus operandi of how Judges and Lawyers ideally operate.

Needs to be more concise to weed out extraneous crap in your arguments
Format: Paperback
It’s very wordy and could be a lot more concise and be even more effective. “Getting to maybe” is not an exercise in dissertations but finding the right points to create an effective argument. There are better resources out there.

This book made me angry
Format: Paperback
I was excited about this book. Many law-related blogs and forums highly recommended this book. It's a "must read" for law students, they said. I was angry when I read the introduction. I was angrier when I began reading the chapters. What happened to brevity? Law students are already swamped with course readings. Why write a book intended to be read by law students in such a long and voluminous way? Much of the text can be removed. "Get to the point," I found myself telling the author as I read page after page. I hated it. It is the rare law student who will pick up this book for its narrative value. The typical law student will pick this book for its value on navigating through law school exams, not for its story-telling. Yet that student will be left disappointed. I wish the author would have considered writing a "Get to the Point" book, which would serve as a shorter version of 'Getting to Maybe.' Perhaps it is not too late. "Get to the Point" could serve as an alternative or accompanying version, maybe? I ask that the author considers this.
