Damn, too steep for me lol...
But in response, Tolstoy, my guiding book has always been Nietzsche's back-to-back books on the power of the individual over the masses, "Thus Spoke Zarathustra" and "Beyond Good And Evil."
Really what I get from those for Diplomacy is the idea that you have to be able to be bold and make decisions and try for great gains without fearing a fall--and if you DO, never quit, try and stay in the game...and if you LOSE, learn from it, because you're only a failure at the game if you never try to win or if you get stabbed and allow yourself to be stabbed in such a way twice.
It's sort of that Captain Kirk mentality...
There's an episode (really GOOD one) where, at the end of the episode, Kirk has stolen the Romulan's big threat to the Federation, their cloaking device, and tells Scotty to install that thing double quick as now they have all these Romulan ships on their tail...Scotty just gets the thing installed in time but says there's a great chance it'll malfunction and fry all their circuits.
And Kirk's response?
"Throw the switch."
If you're going to win or do anything well, be it life or Diplomacy or captaining the Starship Enterprise, you have to be able to give that order to "throw the swtich," turn it on, full speed ahead--take the gamble, because otherwise...well, you'll wind up on the short end of a stab...
