A six-figure job is shooting a bit high (although tbph I have no clue what the average wage is in the Valley or wherever your point of reference comes from), but besides that, this is pretty much what I was going to say.

A stable life and supporting yourself, your mental status and your family or whatever is, imho, more important than trying to live some fairy tale where you build a chat app and get bought out by Facebook.

The startup success stories are all basically lottery winners, probably with similar odds.
