Step 2:
Don't Give Up - Giving up whilst leveling a character in world of warcraft is the worst thing to do if you want to get a level 80 character, i once had a character that was stuck between levels 50 - 60 for a very long time because i gave up on leveling. Then when i actually put these techniques into action i leveled very quickly, I got from 50 - 80 in 4 days!
Step 3:
The Home Straight - once you hit level 70 in leveling in world of warcraft, getting to level 80 need allot of exp! This is probably the hardest part of getting a level 80 character in world of warcraft, but once you've succeeded you will feel very Happy and then you can continue on to earn better gear with raiding, earn extra items for your lower levels, and finally brag to your friends that you have a level 80 character.
