I'm not really seeing a problem.
As long as you are comfortable with your financial position, then it sounds like you're living your best life.
You haven't given us any numbers, so I really can't comment on the level of financial risk you are taking, and it doesn't sound like you are looking for a critique, so I'm just going to assume you have your numbers figured out and are happy with them.
If not, then do a case study and we'll give you customized input.
But assuming your numbers are reasonable, I totally get it. Shortly after I read MMM, I left my extremely desirable, elite, high paying job and demoted myself to a part time, lower stress, lower responsibility role. Then when my health started failing in my 30s, I walked away from my career completely, leaving my much lower earning DH as sole breadwinner.
That said, if you throw numbers, we're in extremely good financial shape and no one would ever worry about us. So I won't worry about you unless/until you indicate that I should.
Otherwise, good fucking job figuring out how to be happy and healthy.
