I once had a conversation with a very, very experienced developer who ran a local meetup and was discussing salary options at a new job. He balked when I told them what I asked for, and replied:
"Just because you grew up as poor as me doesn't mean you should fear wealth. If it makes you feel that guilty take the shit and donate it to charity."
And its really true.
My first engineering job I made almost 3x what my mother ever made in a year over her entire life's highest salary.
I was a college dropout that was enthusiastic and knew enough to be functional.
It really is a strange, new thing to come from nothing and all of a sudden be able to go out to eat at an Applebee's without worrying about your finances for a month.
Edit: The first thing I did after collecting my first 'engineering paycheck' was go out to Applebees and get an appetizer, a drink, AND an entree, and then proceed to not worry about it.
