Well, that sounds like completely the wrong way to do things.

When I reach a new area I pick up all the quests I can and start working on them. Only when I have finished all the nearby quests do I move on to where the MSQ or vector quests points me next. This way my quest log never overflows, and the quests I do all are connected with each other in some way.
After several years of playing various MMOs, I have found this to be the best approach - to systematically finish as many quests as possible in one area before moving on. It makes most sense story-wise and does not leave me with a ton of unfinished quests in my questlog.
