Thanks for that rich feedback, really helpful! Didn't know about the differences between the rich/middle/working class dichotomy, something to keep in mind for a future blog post expansion on this one.

You are right that the 18-year-old me was thinking of job=rest of life, and that's not a great mode of thought. Good point about the career changes as well. As a college professor now, I try to convey both ideas to students. That's why the post suggests revising one's life goals every 3 months or so.

I'm curious about your life planning system. Can you give some more details on how you use it, and some specific examples of how it helped you/others?
