I normally know better than to respond to "career advice", particularly, coming at it from an angle of vulnerability. I think the primary reason I'm doing it is as a service to my younger self (and people in equivalent situations now), which could have been spared quite a bit of heartache, if it had had more people around ready to call bullshit on bad advice.

Moving to SF is only an option for the rich and privileged. Saying no to a solid paycheck that comes with a 40-hour workweek to make space for randomness is for the rich and privileged. Some of us are born rich and privileged, some are not. Some of us are born as extroverts, some as introverts. For some of us, putting off-hours to use for doing more work-related stuff ends up working out, for others it wreaks havoc on our ability to have hobbies, social lives, and families and is a surefire way to destroy happiness (and might still not help our careers).

"Everyone needs to move to SF and start prioritizing hustling over staring at their editors and compilers" is terrible advice. For a sizeable proportion of people it's not an option. For a sizeable proportion of people it's a surefire way to destroy their lives.
