I don't think these points are very relevant. Here are mine (better of course) :

- prefer simple solutions

- makes sure his code will break gracefully

- never prematurely optimizes

- don't reinvent the wheel (i.e. : knows his ecosystem)

- sanitizes inputs

- looks for edge cases

- builds a working solution first, iterate afterwards.

- asks for review

- refactors as needed

- writes sensible tests

Much better. The 'you have' and 'you are' in the post aren't even habits. I want these concrete actionable items.

The 2 points that spoke out to me: - #8 You understand work-life balance Life brings sense to your work the way work extends your life (see #7). - #11 You’re part of the community Think, tinker, discuss, contribute! Exchanging ideas makes you a better professional (and person).
