Memories are a path to your past. Sometimes that path is lit and strewn with flowers, and sometimes it runs through dark tunnels. Are you certain they are important, the memories you are thinking of now? Perhaps you should, just for a moment, stop and see what these memories bring you. Is it an experience which moves you forward and brings a solution to all your current problems?
It is dismal to walk along a path which no longer exists, even if it is strewn with flowers. Go back to the path, see what you’ve learned from it, and then move on down the path which now awaits you, the path where all you wish for can be found.
