To me, $80k sounds like a very small amount of "F-You" money. I'm not criticizing the OP at all, but if I quit my job with 80k in the bank, I would
immediately start researching the most painful B2B problem I could solve
quickly using AI. Not to generate an income stream, but to build an asset (the business) to sell.
That's the quickest path to $1M. Software developers are too caught up on salary (or 73 different "income streams" that all make $0), and rarely think about building a valuable business.
