I won't be subtle. Do yourself a favor and read/listen to this book. Especially if you like to whine and complain. It will serve you well.
Also know that this is an affiliate link. But please don't let that stop you from adding this to your library. In addition to being helpful and thought-provoking, it's also laugh out loud funny in parts. Just ask my seat mates on my flight from Philly to Providence.
