I'm going to type this up and put it somewhere prominently in my office as a reminder.
It's about the process!
"Banish the future. Live only for the hour and its allotted work. Think not of the amount to be accomplished, the difficulties to be overcome, or the end to be attained, but set earnestly at the little task at your elbow, letting that be sufficient for the day; for surely our plain duty is, as Carlyle says, 'Not to see what lies dimly at a distance, but to do what lies clearly at hand.'"
