Waiting does suck. Only good thing about it is it gives you time to get everything in the rest of the quest lined up. I always make sure I have exactly what I need for all the quest in an update or replenish them if I use them.
If you run out of something and wait until the quest is on your game. It will take fffooorrreeevvveeerrrr to get items that are needed. So it's easier to make or get everything you need ahead a time. TL says that their not that fancy but it happens over and over again to everyone.
