How many times of trying do we need before we stop?

Never give up your dreams until a better one comes along.

I am a rather stubborn person who tries keeping past the point of insanity. I do not really accept failure. Rather, I see failure is just a delay from the eventual success. I see what I can learn from each failure and then I go back to the well and try again. What I learn from each situation where I come up short might allow me to eventually succeed in the long run. So exactly how much is too much? Well that is hard to say and that really is dependent on the situation at hand. There are times where we might have to cut our losses. There are times where we might not have the resources to try one more time or the time or the ability. That might be the time to say when. That is about the only time when I think that we just need to throw our hands up into the air and admit defeat. As I said, I am a rather stubborn person. I will always keep trying until the very end. Plus there is always a very nagging thought that is in the back of mind with everything I stop trying. Would I have succeeded if I had tried just one more time? That question tends to spur me on to another attempt many times and maybe I succeed or maybe I fall on my face again. However, I just have to try that one more time, which turns to one more time, then another time, and...well you get the idea.
