Ethics: "If you see fraud and don't shout fraud, you are a fraud" Nassim Nicholas Taleb.
I just love this guy and have read read all three of his books to date, even though they pretty much all deal with the same theme ie; antifragility.
For me the best was the Black Swan but I may be skewed by the fact it was the first of his books I read. Most inspiring of all though is his Facebook blog which expounds on his ideas and invites some very insightful commentary from which I chose the following extract:

journalism requires inability to think about matters that have an infinitesimal small chance of being relevant next January,
...6) But to succeed in life requires a total inability to do anything that makes you uncomfortable when you look at yourself in the mirror.
