I question this myself. I worked over 100 hours a week on the 3rd - 6th version of the iPhone. Did I make a lot of money from working there? No not really. More than I made at the 3 startups I joined afterwards .. but only because I didn't sell my stocks. Did I learn a lot yes absolutely, probably about 5 years worth. Has it helped my career: Absolutely. It's opened many doors. I usually get to pick what I want to work on. Did Paul Graham and Sam Altman both try to convince me to quit and join a yc startup or start my own. Yes at 2 different Startup schools they told me I was wasting my time. Shortly after I did join heed their advice and join 3 separate startups ... with mixed results. Did I work too hard? Ultimately no, because it's like investing in the market. Yes you think you'd rather have more (booze, travel, video game, etc) at the time, but those things don't improve your life in the long run. And ultimately I wouldn't change where I am today for the world ... minus the pandemic / quarantine / civil unrest.
