on being a professional coder

I recently finished Robert "Uncle Bob" Martin's The Clean Coder and I'd like to use this space to share, very briefly, my takeaways from the book, as I head into a new team lead position.

• Accurate estimation of coding tasks is essential if you want to maintain trust between coders and managers
• don't be afraid to push estimation back due to scope creep, etc
• TDD is a way to write better code faster in the long run 
• (I already knew this but it was good to hear it again [and again, and again, and again])
• Pair programming is also a way to write better code faster in the long run
• Never tried this in depth, but I'd really like to. Guess as a team lead that might even be up to me!

anyway I'm inspired to be more professional in my coding life, so I guess he succeeded. Book's a quick read, too.
