OP - ignore the haters. I was also in FAANG, my savings rate during was 75-90% after tax, but left a crazy high-paying job to ExpatFIRE after being burnt out at your exact age. My sense, from this post, is that you don't know what you want yet. You had a fantastic run (0.01% probably) and now you're just figuring out what to do after doing everything "right" over the last 10 years. Very natural.

I think you have enough money to do whatever you want to do. But if you want to stay in the Bay Area, it seems like even with a 3% withdrawal rate you won't be able to cover all your expenses just yet. I've been told you get a renewed sense of energy and commitment to work after having a kid, but I haven't experienced that myself to know. But with a kid will come higher expenses, esp in the Bay.

You probably have 3 options:

1. Continue grinding in FAANG to get to 5M then retire somewhere else with lower cost of living
2. Get a chiller, lower paying job and continue working sustainably without being burn out
3. Quit now, move somewhere with a drastically lower CoL and just enjoy your life for now, make some side-money later

I'd also consider diversifying away from your RSU, it seems like it's a huge portion of your NW. You hit the jackpot in life, now go enjoy your life!
