I love this model. I've been thinking a lot about where I am, and where various others I know are on a scale like this.

I recently developed my own very simple productivity tool that I've rolled out to a small group of my newsletter subscribers. I've gotten the sense that they're all over this scale. The tool I'm using is in a sense trying to make sense and be useful to people at any given level, but ultimately pull you up to at least level 5.

But that brings up a question: can a system get you beyond level 5? That is to say, can a productivity tool or system help you look beyond yourself, fully embody a purpose, truly self-actualize?
