"It works or it doesn't" suggests you either limit yourself to extraordinarily simple projects or your clients don't care what happens as long as it's not a 500

"It works or it doesn't" suggests you either limit yourself to extraordinarily simple projects or your clients don't care what happens as long as it's not a 500. Development is not such a black and white pursuit if you're working on projects with any sort of complexity. I'm better with programming than I am with charcoal, but I can say with certainty that while my art is hanging in a few living rooms, my code gets a lot more scrutiny (appropriately) and evolves much more. That's not because it can or should be perfect, it's because the result and the scrutiny is less subjective.
