I do not think that dusting is the best way to apply my abilities and talents. I can use them in other way. Those people don't apply their resources in any way. That's the difference.
About unreachable.... The question is why they are unreachable - because they are out of your reach regarless of how high you jump or because you don't want to stretch your hand. Even in order the stretch your hand you need to want more candies. Otherwise, you will keep sitting on the couch.
Let's say, i'm happy with what I have. But I always want more. For me, it's normal personal evolution.
