I have an embarassing confession: I am a technical consultant.
I am often asked for book recommendations to help people improve their work. Sometimes this is to solve a technical challenge, other times this is to solve a more human one. This is where I send people.
It contains the books that have changed how I think about work, books I often refer to for advice or practices, and books I think bring together in one place a bundle of advice. I like to go beyond the "tech book", so you will also find books that explain why people are like that.
