It seems like he has a brand that is pretty lucrative, so it’s unclear to me if he:
1. has enough money to be functionally retired at his current lifestyle, but chooses to continue his brand anyway,
2. has enough money to be functionally retired, but not at his current lifestyle, and so chooses to continue his brand,
3. cannot functionally retire and simply “transitioned” from professional software development to professional blogging.
I follow the logic of his blog series (reduce spending dramatically, increase savings dramatically, invest optimally), but I can’t tell how much of it contributes to his current lifestyle.
