I no longer see goals as pending accomplishments but as immediate motivators. Little happens without movement, and movement is easier with a rough outline. Instead of plotting your trip down to the last tenth of a mile, maybe just head north for a while and don’t feel bad if you take an alternate path when you find a boulder in your way.
But if you possess enough dynamite to remove the obstacle, by all means let 'er blow and carry on your merry way. Just remember: Cool guys don’t look at explosions. They blow things up and then walk away.
