Aside from the first question (may first 2 questions), the top questions are arguably more qualitative than quantitative.
> Do I solve more problems than I create?
Who judges what constitutes a problem? How do you know when you've created a problem?
> Do I see simple solutions to complex problems?
Define 'simple'.
> Can I refactor terrible code to more easily maintained code?
Define 'terrible'. How does one know what code is more easily maintained?
> Can I avoid terribly written code in the first place?
See above.
> Can I effectively communicate with people in order to get the answers I need without wasting their time with needless questions?
What constitutes "effective" communication? What are "needless" questions?
I generally agree with the questions, but I would imagine most programmers could read them and think, "I must be pretty effective."
