2) The general wisdom if you want to get financially well-off is what you describe. Those who'd prefer to risk it all for a shot at being filthy rich do startups.
Everyone ELSE on this thread needs to learn how to manage their finances. $93k in Seattle is $65k after taxes, call it $50k after putting $15k a year into your retirement plan.
Remainder: $4100 a month post-tax
You can rent a small apartment within 30-60 minutes of downtown for $1500 a month, leaving $2600 for utilities, groceries, entertainment, etc. That's a good $50 a day left over for food and entertainment, easily.
I'd call that comfortable, personally. That said, I wouldn't take an offer in Seattle for less than $200k and I wouldn't take an offer in Silicon Valley for (SeattlePay+$12,000)/0.9 because of the higher rent and state income tax
