Cecil at Immediate Action Combatives posted this link. I think every one of you should read it.
You are responsible for you. You are responsible for your actions. You do have control over who your enemy will be fighting. You have control over the training you will have had. You have control over what speed and accuracy you will be able to achieve. You have control over whether you are fit enough to move, fast enough. You are in control of everything that you are in control of. Accept that responsibility.
Hold yourself to a higher standard and DO THE WORK.
