This maps with some of what I've been learning, fills in a few gaps, and also strikes me as not quite 'enough.'
There's a bit of frustration that comes when you recognize many of the 'levels' and would aspire to reach them, but life circumstances have kept you in an altogether different level.
I'd warrant that moving between levels, living between them, even, is essential and where many of us actually might be. Levels are fairly subjective, after all. What is important to one person isn't necessarily important to another.
For me, the different levels aren't really what I find important - it's whether I'm growing as a person alongside making a living so I can support my family. Most people won't be able to stop 'making a living' - far more people will have to do one job while dreaming of doing something far different. But beyond making a living, life awaits.
It's what we do with the whole of our life that determines how successful we truly are. And I don't think that translates as well to the idea of levels.
And yet, I do see the appeal. We tend to come up with arbitrary and subjective individual levels. Some of us will be 'stuck' for years before we aspire to something more. Whether that something more is to accept something, move on from limiting beliefs, or grow in knowledge ... most of us do aspire to something else, something more.
