“A quote to live by from a Sergeant Major from Infantry School Delta Company: `The toughest muscle in your body sits between your ears.' If you can control, that, everything else becomes relatively simple. It’s all about determination. You live of fail by what's between your ears. No matter how tough you think you are, or how big you think you are, if you don't have it right up there, you're not going to make it. Out of all the things I learnt from Infantry School this is what stayed with me.”
