The main takeaway for me is that people forget how to be frugal. Hopefully I'll leave grad school having learned more than just CS - given how I spend these days, I can't imagine ever blowing that kind of cash while unemployed.
It may sound shallow, but it's not an entirely negative thing. A fireman enters a burning building, he's afraid sure, but his self-identity is the hero, he's not going to back down, he's more afraid of the shame.
