I would have to say that QDM is "easier" to practice for those of us who do see many deer. I passed on more deer this year than I care to think about, those I pass on I try to "shoot" with a camera. It's not quite the same, but it provides good practice getting into a position to shoot. After seven seasons, we have spent quite a few hours turning our 100 acres into a great place to hunt. But it took a lot of hard work with just two of us. We're pretty proud of what we've accomplished and that is where QDM comes into it.
I'd also agree with gunther89, it's better to start out small. When I first started hunting I would shoot any deer that was legal, I was just anxious to shoot one having never done it before. Then a couple years into owning our place antler restrictions came along and forced me to be choosy on the deer I shot, finally with a few more deer under my belt (all does), I suddenly no longer had the same "need" to shoot a deer and waiting on the 3.5 year olds or better became a whole lot easier.
I don't hunt to fill the freezer, I hunt for the enjoyment of the sport, being in the woods, and the feeling of accomplishment I get from seeing our hard work pay off with more and healthier deer. If filling the freezer was a priority I might well feel differently, but I truly believe that quality QDM will provide a healthier herd, will provide more deer, and will provide more shot opportunities if a person is willing to give it a chance.
