Excellent advice, I agree 100% with this. Also I want to add that allocating time for a refactoring or fixing legacy code is hard to justify most of the time.

Excellent advice, I agree 100% with this. Also I want to add that allocating time for a refactoring or fixing legacy code is hard to justify most of the time. Instead I try to follow the "boy scout rule": On every bug fix or new feature you work on "Leave Things BETTER than you found them". An small change like properly naming a class or a variable, or just writing a readme file explaining something will help you and your team in the future. https://medium.com/@biratkirat/step-8-the-boy-scout-rule-robert-c-martin-uncle-bob-9ac839778385 https://medium.com/@biratkirat/step-8-the-boy-scout-rule-rob...
