Giving Up

I sprayed some insecticide on a fly which was getting on my nerves while I was studying. It fell down and I started watching it while it was slowly dying posioned. It was struggling indeed. It didn't want to die, so it fighted as much as it could against the poison I had sprayed on it. Such was the effort it was doing that I thought it might be able to live!
But suddenly it gave up and in matter of secods it died.
Then I thought:
What if it didn't give up?
What if it just kept struggling till finally beating the poison?
I don't know, and I will never know because it gave up and died.
Never give up. No matter how strong the poison is.
Never give up. Because giving up is the only way you will lose or die.
