The times when I made the most improvement in a particular skill comes from not-dull, constant practice. Hard, yes, repetitive, yes, but never dull. If your attention wanders while you are practicing, you're not getting the most out of the practice.

Lacking confidence tends to distract as much as over-confidence. The person practicing stops paying attention to what he is practicing.

I'd say, transfer of learning (taking advice from one context and figuring out how to apply it in a different context)is a form of resourcefulness. (Though I'm more of the opinion that resourcefulness applies to both internal and external obstacles).
