f you don't have the time, wait until you do. No timetable is the only way to go.
Great philosophy but not practical. Some may never make it to "no timetable" or for other reasons may never have the time to "stroll". I'd rather see a place briefly than not see it at all. One of my favorite trips was 7500 miles in three weeks when I used to tent. Did I spend as much time as I wanted to at the places I saw-absolutely not-but I've got one helluva war story, some of the best memories EVER and would never want to change the experience. Now I do things much slower than I did back then and spend time revisiting some of the old places with a new appreciation. It's all in what you make of it.
