I'd be foolish to ignore the possibility

i do not understand why is stubborness considered as a bad personal quality. i mean winner never quit, quiters never win, right? so when you give up after even a tiniest obstacle, then why to even bother start fighting. i usually go after what i want and don't give up after all the hope is finally gone and burried, because if there's even a little hope that i might succeed then why should i leave it like that, or i have caught that? take a chance, make a change? yes, surely. and i do it in personal and professional life. well previously did in personal, now also in professional life. i've been always on oppionion that if you do not take chances, you'll regeret it afterwards, like what would have happened if i tried a little bit more. if i have used all possible and impossible chances, then i have no regret, i know what happened when i tried a little more. it might take some time and courage to run against the wall, some have it, some don't. some are willing to run against the wall more than once and just maybe if you have run enough times with good amount of courage, speed and power that wall breaks down and you'll have what you want. but here comes the catch. what bothers me about my stubborness is that after chasing something for long time and then catching it, i lose my interest in it quickly and continue wanting it only because i have worked hard for it. they say that chase is better than catch. so that means i need something to chace after, that triggers my interests and i will never completly catch it, only pieces, because even the most stubborn people give up after some time when they don't see any results, that would really intrigue me. only show me what that might be?
