To start something new, you need to go back to where you have started, everything becomes clear from that point. Everything needs a change at some point of time, nothing last forever....Though for the day 

Sometime, it is best to let go of  things that disturbs and distracts you from reaching your goal. until and unless we let go of old things and memories, we will never get the opportunity to look for new opportunities  that awaits us in future. So, for the time being all i am doing is letting it go and walk through the new horizon. let it go, follow your heart and don't be afraid to walk through new and uncertain path, we will never know what lies ahead of us. Walk through.......... :)
