The Clean Coder

Depends on the audience. Generally, it's always "Getting Things Done" and "So Good They Can't Ignore You". For fellow programmers it's "Clean Coder" and "The Pragmatic Programmer". And I always wish my managers and tech leads read "The Mythical Man-Month".

To the point of the question I would much more recommend "Clean Coder" by uncle bob, which mostly deals about the professional ethics of software development

I have all of these on my shelf. Fantastic reads. * Extreme Programming Explained by Kent Beck * Clean Code and The Clean Coder by Robert C. Martin * Soft Skills by John Sonmez (1st edition) * Pragmatic Programmer by Andrew Hunt and David Thomas * Working Effectively with Legacy Code by Michael Feathers * The Mythical Man-Month by Frederick Brooks (Selfish plug) Additionally, I wrote my own book concerning the entire industry, from just starting out to becoming a self employed consultant when you get sick of fulltime work - all soft skills from my decade or so of the industry, as well - https://www.amazon.com/dp/B0B43V1JJW

After Clean Code, also check out The Clean Coder. Less technical, more career/project focused. There's also Clean Architecture, but I haven't read that one yet.
