You can not enjoy World of Warcraft to its fullest unless you reach a higher level. Read our low level power leveling guide; try to level up as soon as possible.
Leave newbie zone when you at level 11, and begin to do real power leveling. Complete the easiest quests in the first area that you go to (Night Elves should visit Darkshore first, Dwarves/Gnomes should visit Loch Modan first, Humans should visit Westfall first.) Move onto the next zone, and do the same, but this time you can complete more of the zone. Leave the most difficult, unless you can get a group for them - don't waste too much time on it, though. Move onto the last zone and complete all, or nearly all of the quests available in that zone. By this time, you should be about level 17-18. Go back to the first zone, and complete the rest of the quests there. Do the easy quests in Redridge, which should take you up to level 21 or 22. Skip the more difficult quests unless you have a group for them. I'd skip the entire Stonewatch Keep area of quests just simply because that entire area itself is crap.
Start at either Duskwood or Wetlands. This is where "quest stacking" can come in really handy if you want to be efficient. There are many, many quests that send you to the same areas, and if you get all of the quests at once, you can knock all of them out without having to run back and forth. Considering Wetlands and Duskwood are fairly bad for having their towns on one side of the map and the quest mobs/areas on the other side, this saves a lot of time. A lot of these are parts of quest chains, so honestly it's hard to know if you don't have prior knowledge or do a lot of quest research beforehand - so don't worry about it too much, but try to be as efficient as you can. Once you finish one of the two new areas, you should be about level 25 and can go finish the harder parts of Redridge, and then finish the last zone.
