  1. Complexity is incremental: you have to sweat the small stuff.
  2. Working code isn’t enough.
  3. Make continual small investments to improve system design.
  4. Modules should be deep.
  5. Interfaces should be designed to make the most common usage as simple as possible.
  6. It’s more important for a module to have a simple interface than a simple implementation.
  7. General-purpose modules are deeper.
  8. Separate general-purpose and special-purpose code.
  9. Different layers should have different abstractions.
  10. Pull complexity downward.
  11. Define errors (and special cases) out of existence.
  12. Design it twice.
  13. Comments should describe things that are not obvious from the code.
  14. Software should be designed for ease of reading, not ease of writing.
  15. The increments of software development should be abstractions, not features.
