Shallow, biased and significantly overpriced
Format: Paperback
Well, this purchase was a disappointment. 20% of the pages are dedicated to just highlighting the bios and backgrounds of the many different authors that contributed this great wisdom. And let me be clear, the authors are solid. They are professionals with credible backgrounds and experience. But it's the format and constraints of this book that makes it virtually impossible for that to shine through. Because the rest of the book (80%) is dedicated to the so called "97 things every cloud engineer should know". And unfortunately the average length of one of these "things" is about 1.5 pages long, and as such extremely shallow and in about 30% of the cases straight up promotions for specific company services. You will find Google cloud advocates telling you to use managed services, of Google of course. AWS engineers telling you to avoid them and use IaaS. LaunchDarkly employees telling you to use feature flags. The list goes on. The TL;DR: here is that if you have built anything on the cloud in the last 2 years, this book is going to be a waste of your time and money. You are better of googling: "cloud best practices" and dedicating 2h to reading the first 10 non-ad related search results.

Improve Your Relationships
Format: Kindle
In Relationship Goals, Michael Todd has written a book that discussed marriage, dating, and even singleness to help us to grow in our relationships. He wants to help readers to win in relationships and he encouraged us to read the Bible and set goals to improve our relationships. Godly relationships consist of sacrificing for others, displaying kindness, integrity, forgiving others, and loving others. Scriptures declare that we must first love God with all our heart, soul, and mind see Matthew 22:37-38. We are also called to love our neighbors as ourselves (verse 39). He explained how we are supposed to have good relationships with others even if you are introverted. One of the keys, he uses is asking himself does this relationship help me. When we meet the right person, they will help us toward our purpose in life and they will believe in us and love us and they will fit. But if they are moving you away from God, run. He shared how he met his wife when he was 15 years old at a mutual friend’s birthday party. He did everything to make sure she noticed him. This led to a spark and they dated for 8 years except when they experienced an 8-month breakup and he explained what happened. They eventually reconnected and got married in 2010. I liked how he talked about lot about singleness and how in this time of our life could be the most important time. The reason why is because it’s a time we can focus on what God wants to reveal to us about ourselves and who we are. We are become self-aware and find purpose. This can help us to become whole before we commit to someone else. This is a critical time to heal from our past pains and deal with our fears. You can use this time to get closer to God and getting to know Him. I would recommend this life changing book to anyone who is ready to improve their relationships it doesn’t have to be just romantic relationships. The same principles can apply to friendships. This book is a very well written book about dating and marriage and how we can change the scope of our relationship. I also liked how he explored the important keys to having a good marriage and what men need and what women needs and the differences. He tries to assist readers in understand each other in marriage and I believe if readers really tried to work on these lessons, they would be less divorce and our marriages would be a stronger example to our children. This book is an awesome book for couples to read and reflect on.

Best Relationship Book!!
Format: Hardcover
First, I wish I had this book 25 years ago. Sure, I had the Bible and knew all the Christian 'rules' but Rev. Todd lays everything out so well, even the details that have gotten lost or glazed over through the decades of Christian teachings. The way he presents each phase is superb! I love, love, love his authentic writings on God's love for each of us. You can tell Rev. Todd is a man of deep faith but most of all, he is just a person that, like all of us, mess up. His writings are real, authentic, relatable, inspiring and exactly what this world needs. I do hope Rev. Todd continues to write on other topics. I have been truly blessed by this book!
