YMOYL didn't resonate with me, probably because he lived in an old house in Berkeley with a bunch of roommates, wore Birkenstocks* and pretty much eschewed the stock market. Not the lifestyle I aspired to.
What did it for me was "The Tightwad Gazette". Completely life changing for me. Amy D started her famous newsletter in 1991 and retired in 1996.
*Nothing wrong with Birks per se, they're just horribly uncomfortable if one has long, bony feet.
