If you were to count them, how many lives have you had already?
If time is like a river, how many branches does it have now? How many decisions did you have to make? How many people did you have to leave behind?
It is its course that changes with your living, with your deciding. It is the flow of the past that drives you to the future, and if that's the case, why are you swimming backwards?
You can only move forward, take the best of each day and create new paths, for the paths of the past can no longer be changed. It is today when you can act; it is tomorrow that you can still change.
While you must not forget the past, remember that it is the present you must walk, and with each step, create your future.
