1. Ship it and iterate. 2. Make changes small, make them often. 3. Technical debt is a useful tool. 4. Solve problems at the root. 5. Do not accept deviant system behaviour. 6. Write code to be read. 7. Write code to be debugged. 8. If you can’t show it’s a bottleneck, don’t optimise it. 9. Unblock others whenever you can.

  • 10. Leave the codebase better than you found it.
