Everything is Awesome! (10)

Awesomefish can be caught and found in Draenor. Target someone you think is awesome, and throw it at them. They'll get a buff that lasts 24 hours.
Friend or Fowl? (10)
Slay 15 turkeys in 3 minutes.
Giddy Up! (10)
Learn the apprentice riding skill.
At level 20 you will be able to learn the skill that allows you to mount (unless you have the heirloom mount). You will be able to mount at the slowest mount speed (60%) and won't be able to fly.
Fast and Furious (10)
Learn the journeyman riding skill.
At level 40, you get journeyman riding. You will be able to mount ground mounts at 100% run speed, but still won't be able to fly.
Into the Wild Blue Yonder (10)
Learn the expert riding skill.
At level 60 you get expert riding. You will now be able to mount flying mounts.

At 70 you get to buy additional flight speed.
Breaking the Sound Barrier (10)
Learn the master riding skill.
After you hit level 80, you will be able to pick this skill up. Speak to the flight trainer to train, but it's expensive (around 5k gold) so be prepared.
Going Down? (10)
Fall 65 yards without dying.
Falling into water doesn't work, but slow fall, ice block, and other mitigation will still allow you to get the achievement. Some instances drop you and you also get the achieve.
Got My Mind on My Draenor Money (10)
Loot 10,000 gold in Draenor. Unlocks: Storehouse, Level 3
Run lots of stuff in Draenor.
Got My Mind on My Money
There are several versions of this achieve, each one increases the amount of gold you need to loot:
100 (10)
1,000 (10)
5,000 (10)
10,000 (10)
25,000 (10)
50,000 (10)
100,000 (10)
200,000 (10)
Best way: loot lots of mobs...open lots of lockboxes and other such satchels...
Greedy (10)
Win a greed roll on a superior or better item above level 185 by rolling 100.
Best way to get this is to run lots of stuff in a group and roll greed on everything that comes up. Only blue items from Lich King and beyond will count from this (check the item level).
Needy (10)
Win a need roll on a superior or better item above level 185 by rolling 100.
The best way to do this one is to get into a group of friends who don't care (or where everyone is needing) and then roll need on everything. Alternatively, you can be in a group but be the only one in the instance (if your buddy is off doing something else). Because you're in a group, you'll have to roll on everything. Lich King items and above are the only things that qualify for this achieve.
It's Happy Hour Somewhere (10)
Drink 25 different types of beverages.
The best way I've found of doing this achievement is to go around to the various inns and vendors and buy drinks. Food doesn't count for this achieve. Also, stick to stuff that requires lower than level 70, since Lich King stuff doesn't count for this either.
Tastes Like Chicken (10)
Sample 50 different kinds of Azeroth's delectable dishes.
The best way I've found of doing this achievement is to go around to the various inns and vendors and buy food. Drinks don't count for this achieve. Also, stick to stuff that requires lower than level 70, since Lich King stuff doesn't count for this either.
All of these are items that you can cook. As you level cooking, you will receive recipes for them. Gather the materials, cook them, and eat them to get this achievement.
Reach maximum level on both an Alliance and a Horde character.
Level two toons to max. They don't have to be on the same realm, just same account. It might possibly work if you switch factions (level one to max then change).
Dynamic Duo (20)
Reach maximum level with two different classes.
Make 2 toons, level them to max and you have this achieve. Running dungeons is typically the fastest way to level.
Terrific Trio (30)
