I got a the highest paid job I could find with the skills I have that I enjoyed "well-enough". I spent less than I earned. I made mostly low risk investments (with a handful of high risk investments). I consistently did those behaviors for many decades. I also got lucky that nothing bad happened to me.

I guess if you follow 'The Four Hour Work Week" but don't endlessly promote yourself through books, articles, podcasts etc?

By the way I think the Four Hour book is a bit phoney in that he makes out that's possible but was actually working like 16 hours a day building his own thing.

I guess MANY people are "famous" within some limited group. I suspect few here (much less more broadly) could name senior execs at the majority of large companies who are mostly wealthy by any reasonable measure.
