What does "Don't Quit," mean to you?

You would have to kill me, strip everything I have, and take everything from me to get me to stop. That's how it is. I suppose if you knew me then you know that I start my training late at night when everyone is fast asleep. I push myself to the point where I get dizzy and sometimes throw up. I move a little more and do one more when my body trembles. But you wouldn't know this unless you know me. I guess you would think this is all temporary and I am doing all of this specifically because I am training for this event. Well what you didn't know is that I'm not in the business to impress people for the sake of just doing this. Every moment I make a decision its with a greater purpose in mind. What if I told you this wasn't the first time I pushed myself to the edge of my own personal boundaries? What if I told you that I have gone days without food before? What if I told you that I have gone days without sleep before to the point of collapsing into a convulsive seizure? What if I told you I destroyed ligaments and broken bones in the service of my duties and yet continued to press on? Sometimes its easy to say dont quit when you dont know why you are going in the first place. I know what this means to me because its not cliche. So... what does "Don't Quit," mean to you?
