I like the "after getting hired" quotes; they're all good advice that benefit you, the only caveat is to make sure you aren't getting taken advantage of. Don't overwork yourself to enrich someone else; enrich yourself first.
Who cares if your boss is getting some great deal on a $ basis if you're getting the experience to be the boss?
My advice in this piece is for people who aspire to accomplish great things in their life--not folks who want a "great life" (defined as balance, vacations, etc). So, if you're 35 and have a family this isn't the advice for you (that should be obvious).
