Motivation for Writing Code

  • Collaborating with others to produce the best possible codebase/project.
  • Continually learning and refining skills and technique (the craft).
  • How good ‘clean code’ looks on the screen.
  • The feeling when an insurmountable problem dissolves.
  • Constantly refining.
