One of my goals for May 2018 was to finally read The Pragmatic Programmer. I haven't succeeded yet, that's why this year, June was May, Extended Edition and July is June, Extended Edition.
A few years ago, a dear friend of mine recommended reading this book to me and I should have listened to him. It is so interesting to read, I've learned a lot of things and I'm barely halfway through. What I like about this book is that it encourages you to think about your work and how you achieve it. It shows you good practices without being arrogant.
