I was wondering whether commercial curiosity is a skill in the traditional sense? Would commercial curiosity be considered a skill which a commercial solicitor would require to succeed? I've included it as a skill in one of my answers, but I'm concerned that it sounds like a trait rather than a skill.
I would personally say a commercial mindset is more appropriate as a skill (although don't quote me on this as I don't know if the application I used referencing this skill was successful yet). Being able to see commercial issues from your clients perspective (eg risks, opportunities) is the way I understand a solicitor's "commercial mindset" in practice.
Hope that helps
