It would have been more interesting that he writes on how it was complicated for him to reach financial independence even when he earned 100k/year from day one and more than 600k/year 12 years later. Just imagine how it's impossible for someone with 47k/year! And that's the MEDIAN salary range in the US! But apparently that thought escaped him, whatever.
