Very nice writeup, quite thoughtful. It took me a couple of reads to understand it, but I think I got your point.

I would add to your list:

Humility

Leave the ego by the door when you log in. Downvotes and upvotes don't reflect on you as a person. If you get downvoted, consider whether it was deserved: could you have done better? If so, learn from the experience.

Reality

XP is a figment of vroom's imagination. Don't get hung up about it.

Diversity

There are a lot of monks out there, new and old. You may be unjustly downvoted or upvoted, sometimes for reasons entirely unrelated to the quality of your post. Live with it; it's easier to change your attitude than the behaviour of 12,000 monks.

I did ++ the node, in case you were wondering. ;-)
