Walking away from something unfinished...

Many a times, things dont go your way.. its not that u were destined to go through all that but sometimes it just happens. you are almost tempted, initially to curse, and then later on to try and figure a way to run away from it. running away sometimes leaves so much of mess that u cant really turn back, even at times when u want to. Does the happening of this situation always get us back on the track? or does it tempt u to still stay the way you are? the consequences, do they act as a hing of the past that has gone by.. that is never going to repeat itself.... or does it push you over to bring about that much needed change that would prevent you from falling into the trap once again?? ..... really... is it worth spending time brooding over somethings that gone by, moving on and thinking it as being one's past... or rather breaking it down to see if it has substance to help you enrich your basket of experiences??? A million dollar question... and i guess it stays so this way.....
