Reading that felt strangely liberating. It's a refreshing and eloquent reiteration of the whole idea of the goal being the journey and vice versa. Contrary to what modern society has instilled in us..
Or in more general terms, focusing on the journey instead of the goal leads to complete detachment from reality - running in circles and enjoying the patterns of your own thoughts, like a stoned hippie. It's vegetation, not life.
I do read Adam Smith's quote differently - the way I understand it, it says to focus on a goal, but to derive happiness from the process and make that happiness independent of whether or not the goal will be ultimately achieved. An impossible thing to do in full, but definitely worth pursuing.
Sounds pretty attractive to me
Edit to add: Just noticed one of your other comments, on paying attention to driving :)
(Then again, we wouldn't have most of our problems in this world if we just stuck to being stoned hippie self-wireheaded cavedwellers ;).)
