> I'd probably start to objectively define those opposite things you are setting up against, ASAP
If I have a list of these things, does it act like a checklist for me, whether something would be worth pursuing in future or not?
I would be really hesitant to give a checklist to the person you've described, but maybe if it really motivates you? I would rather see a qualitative exploration, something much deeper or even overlapping with your current concepts for curiosity's sake. For example could you somehow map the concept of excellence onto who you already are? I think you could, and maybe one result is something integrative of both aspects of excellence & appreciating the day-to-day, like Tom Hodgkinson's _How to be Idle_, etc.
So the exploration and its nuance would probably be worth much more than the checklist itself, just a guess & IMO.
