I finish the book within two weeks, I just can't put down the book because it almost felt like the Azelbys' brothers are speaking and tell me off to my face. Like hey, listen, "Here's your but! Sit down and finish this before you start to whine at work!"
Whether you are working in a corporate world (there's dozen of situation examples that you can resonate to!) or not, after reading this book, you will definitely want to sit down at a corner to think hard on what's your real BUT that stopping you from achieving your potentials.
Once you have done all that (be honest with yourself! you have too... cos no one is watching, it's just the Alzerbys' brothers words and you) you will realise, how much time have you wasted at work, whining over things that have solutions and not even worth to sulk about. Most of the time, it could be others (depend on how we perceived the situation) that is uncontrollable, but MOSTLY IT IS ABOUT MYSELF (AND YOU TOO) and it is something controllable and changeable! This book not just helping you to identify your BUT, create awareness around to slap your BUT but also make you realise how high or low your EQ is in dealing with a crucial situation (ie. the blockers between you now and better you in future). I would use this book as a reference cos the scenario examples are something that you will usually experience on a day to day basis (at work or personal)
