This is a wonderful book about software professionalism. I have heard Uncle Bob on YouTube plenty and have already been converted to his philosophies of clean code in implementation, but I have never had a mentor in my roles since I end up being the most senior individual on the team. He discusses this problem in his talks frequently, how more than half of us are new to industry because of the rate of growth, but effectively we end up relearning the same common lessons over and over again as if it were the first time instead of leveraging the experience of our seniors in industry. Read this book to gain a lifetime of lessons learned, distilled down to the core bits. There’s not much fluff, other than a story of how the lesson was learned, but taking those principals back to my own work, I can see how just in a few years my career has made multiple examples of his findings. I regret not reading this sooner.
