Just keep doing. I use my head, and my mental powers of anticipation and planning, too much sometimes, to my detriment. There is a difference between standing and looking down the road, wondering, worrying, and actually pick up your feet and walking. Just keep going, finishing will take care of itself.

I don't know about you, but I have a hard time following the advice to just "enjoy the journey." I believe that it is possible, and I believe that in order to be able to enjoy the journey I need to develop my patience.
