This guide is for those who prefer to grind out their levels. Hate questing or just don't want to interact with the in-game story? This guide is for you. Stock up on some Dew, pizza, snacks, and some good tunes and you're set. By the way, this guide works best if you're playing a killing machine.

We have no intent to update these guides for Burning Crusade or Wrath of the Lich King content.

Before You Start
Get and install the free Catographer addon. Cart gives you maps of each zone and the level ranges for the mobs and instances in those zones. Want to know where to go next? Just hover your mouse over any zone and pick the one that's right for you.
Buy the biggest bags you can afford (Frostweave bags have 20 slots)
Stock up on buffing foods
Stock up on bandages and keep your 1st aid skill maxed.
Set yourself up so that you don't have to go to town very often.
Upgrade your weapon(s) every few levels.
Consider getting the local "kill X of this beast..." quests for more XP, if you're going to be killing them anyway...
Learn to use HotKeys and macros and then memorize them. Your grinding will be much faaster and more efficient and somewhat less tedious.
Get the skinning skill if you're killing beasts. The gold you make from the skins will buy your level 30 and 60 mounts. If you like, kill a bunch and then skin them. Feel free to skin what others kill.
If you have a choice between killing beasts and humanoids go for the latter, the drops are better.
When you hit Outlands and Northrend start doing the quests.
But what if you actually want to level fast? Far faster than grinding? Then check out Zygor's Automated in-game leveling guide.
