What is the quickest way to make money when playing World of Warcraft?

I've been playing World of Warcraft and am at Level 10. Other than learning a trade and having a job (which I have), are there other ways to accummulate gold quickly?

Ok lvl 10, drop the professiona and pick up 2 gathering skills, like herbalism and skinning, this will add to vendoring money and maybe selling it on the AH depending on the server you play. Then try to pick up some large bags, pick up all the stuff you can, any greys..white, greens anything you can get your hands on pick up, then just vendor it or sell it if someone can use it. Remember by the time you hit lvl 40 you can drop one of your gathering skills and pick up a profession, its a lot easier this way believe me (Ive done this on a few toons and it takes alomost no time to get a profession up that high at lvl 40)
