Getting ahead ... ?

On this morning's walk I was "struck" with the thought ... don't get ahead of yourself. That, as you can imagine, got me thinking. How could I possibly ... get ahead of myself? I realized as I walked through the forest that my mind has a tendency to race ahead of where I am. If I allow myself to dwell on those thoughts ... I am, effectively, ahead ... of myself. Now dreaming and wondering don't thoroughly qualify as ... "being" ahead. Those are just fanciful exercises in fantasy ... not futility!
