You know there are moments when you turn your head back and look what was left behind .
It's okay to look behind at the remnants of the time and the memories .But that bleak source of light , is the end of tunnel from where you had once begun.It seems more promising because you're in dark and you don't know when shall it end.That only source of light you're familiar to is that beginning.
Before even considering this option just remember why did you set your foot out at the first place ?? Why you had to walk down a dark hollow tunnel ??
That light is not your rescue.Few steps have now changed into miles. You have walked miles from there on your own.Now , don't go back.Don't give up !
You can't see the other end it but doesn't mean that there is no end to this journey.Don't forget your down a tunnel and it has to have two ends , one from where you had started once and other one which leads to the END.....
Past can look good but once you decided to move on then do it .
Stop questioning your own beliefs , all the assumptions you made during the long journey are right, they're right. Believe in you.
Its easier to run back but when you will reach there nothing is left.Everything changes , nature alters it course why you want to pursue it back ?
Just walk a little more my friend .....keep walking.
