Agreed. Another way to put it: 1) Honesty. 2) Treating others the way oneself would want to be treated (the Golden Rule)--from this one can derive testing, the right amount of documenation, observing, communicating, working well with others, so much. And 3) the ability to think something through patiently, thinking of what should happen, and what could go wrong, and being willing to develop the skills to make a ~"plan" (i.e., a program) that will do it properly.
