Quests may be repeatable or not; quests may be timed or not; some quests once failed may be attempted again immediately while others requires the NPC to forget about you, which may take a very long time.
You can keep track of your active and completed quests by using your Quest Log. As you find more and more characters that require your aid in various matters, you will take notes that you can reference in the future in case you forget what you're trying to accomplish.
