I'm also 19 months in to retirement, but you are more conscious and articulate! From your list: 4, 12, 20, 26 work for me. Couldn't be happier.
The only item I'd add is "gratitude". My wife and I come from supportive families, but once we left home there was no financial support. We earned FIRE on our own. Some might be cocky about this, but I am full of gratitude for those who coached, supported, advised, tolerated, encouraged me/us along the way as well as for the healthy capitalistic environment of our generation. All this allowed working hard, LBYM, and prioritized in the budget but simple investing to get us to our goal.
