Getting in requires connections as well as professional ability; otherwise, you have no chance at all, so you'll quickly find out where you stand.

If you want to earn this much, it naturally means hard work. It's simple: if you're not part of the last wave of the fifth-grade generation benefiting from the economy, then you're in a frontline position. Don't assume that everyone above you is competent—otherwise, why would they hire you and pay you so much? People do quit too, so don't think you can take it easy here. I'm telling you that upfront.
