How to win at software engineering, in 47 words:
Ship, test, refactor, document, and review.
Build, automate, measure, debug, and deploy.
Read code, write daily, delete often, question specs, and ignore the hype.
Make these habits. Say no to everything else.
Avoid tech debt, scope creep, ego, burnout, shortcuts, and pointless meetings.
Relax. Mastery is inevitable.
