I'm actually reading 'World War Z' again! It's incredibly realistic and it's written as an oral history through interviews with different characters. Max Brooks wrote this book in so many different voices. There are about forty or so. It's incredible. When I finish 'World War Z' I'm going to go back and start again on the 'Game of Thrones' series.
We need to accept that we won't always make the right decisions that we'll screw up royally sometimes - understanding that failure is not the opposite of success it's part of success.
