Hi, if you want to learn about leveling in WOW, I want to let you know that leveling guide are divided into two: hordes and alliance. First of all, there are few rules I learned about world of warcraft and that are:

• Don't find group, if possible.
  
• Only spend Talents on something that could help you kill fast. Why: because it will help you to kill more in less time. (More experience for you)

First of all, you need to learn how to wade your way through the Barrens, and you can do it easily by following Ultimate WOW Guide. Another way of doing it is by reading Hosho's Guide to the Barrens which will help you to level up to 20.

From that level, you could use Jame's Horde Leveling Guide to level up. The two rules I have above are what I learned from him. It's a good rule to play with. Since giving too much link outs ain't good for Hubpages, so I hope you find your way using Google.

WOW Leveling Tip

One of the tips that I have learned is you need to focus only on one area first. This is important because when you focus only on one thing, you tend to level up faster. Focus only on one thing that you believe will increase your level of success.

Somehow, I think most of the wow leveling guides are just plain ol' crap because it's so hard to follow. But you can always try to use those who have addons inside like those listed in wow secret guide. It's a simple website with 3 guides reviewed (you can see comparison of all three at the bottom of the page).
