That One Last Try

Being a Doctor is a hard and badass job, in the OR when a person crashes and they have to start the resuscitation process they try and try until they find a heartbeat, sometimes it works sometimes not so much, but what I fail to understand is how do they decide it is time to stop trying, how does anyone decide that?

Have you ever been in a situation where you are trying with all that you have got to complete a task  but it just doesn't seem to workout and just when you think may be it is time to give up, this little thing inside of you wants you to try one more time and this ends up to be your eureka moment, but  how does one ever know that if something is worth that one more try, worth walking that extra mile?

The same is with relationships I am sure all the people who ain't together anymore must have tried to make it work and revive the magic again, but for all those people for whom things didn't work out how did they decide it was time for them to stop trying?

It is always said you never give up on your family because they are family. I would never give up on mine, they are super awesome after all but how do you decide on other things. Your dreams, aspirations,those other people who ain't related to you how do you decide they are worth that one last try. I am trying to make sense here I really am but after writing this I have realised may be you will never know who is worth that one last try,but may be you  still have to keep trying cause some people are worth melting for and you wouldn't realise who they are unless you try one more time.
