Half the fun for me is making them efficient...I exercise my mind as much as I do my fingers when playing lol; granted, I do have 3 years' worth of playing and a photographic memory so I know where everything spawns right down to how many there are in some cases =x

So I can sit there, look at what quests I have, what their objectives are, and plot a perfecet round-trip of the zone to maximize the efficiency of the run, not heading back until either all the quests I can stand are done or my bags're full and I gotta sell so I keep my money up for later training. I have used wowhead in the past on quests I hadn't done or didn't seem to be getting the drops for but for the most part, Blizz is pretty straightforward in till you where to go and what to kill and even how to kill in some cases lol
