Thought provoking post. I would add determination as its a bit more action-orientated than perseverence. My thought is that the latter could result in doing the same thing time and time again & getting the same result, but maybe that's my interpretation of the meaning of the words.

Also I would suggest that creativity and flexibility are required to think through problems and find a way over, around or through that problem, and adjust to the marketplace, or identify future trends and make changes earlier than competitors.

The latter point being relevant to our presence here on Steemit!
