If you can find any other place that will pay you anywhere near as well...
The key to Silicon Valley is too live well below ones means (think ramen and sleeping on couches), until one can save enough cash from that 6 figure starting salary to move far away and buy that big house on 10 acres in some other state (not CA). I know several engineers who did well on that plan. But that lifestyle choice is certainly not for everybody.
Umm (even while making > $120K) so you need to suffer and live miserably for a few years (eating ramen, sleeping in couches), until you can finally save up to live comfortably in the years after.
Ummm.... those lost years of living miserably, you'll never get it back. 🤷♂️
