Is It Ever Okay to Be a Quitter?

I realized, its okay to be a quitter, sometimes. Under certain circumstances, it is okay. If you are doing something very bad like drugs or gangs, its okay to be a quitter. I think it was okay for Jonathan to quit the war because he was only a child, and hadn't realized the truth of war. But, if its something thats going to actually help you and benefit others, then its not very good to be a quitter. Its acceptable, but it'd be better if you didn't. But, if it is in a cituation that invloves getting hurt, physically or emotionally, then it would be better if you were a quitter. Perhaps, even the world's greatest leaders were quitters at one point.
