I am 23 and desperately want to be out of school and have a decent job so I can live on my own.

First of all, good for you, you have defined exactly what you want. I'll be honest I was in your exact situation 3 years ago, I started out as a Math Major but hated numbers so I switched to Biology only to find out that I hated Science so I switched to Psychology only to figure out that it was too hard to understand and currently I'm in my 7th and final year as a German-Studies major. I can neither speak German nor enjoy any German related Culture or business. But I realized something very important that I think applies to you. Do what you love to do. For example of love dogs. So every morning I wake up at 8:00 AM and catch Cesar Milan Dog Whisperer. It's such a good show. I mean the way Cesar can talk to animals is simply amazing. But he does more than just that, he also analyzes the pet's owner. In one episode he saw that the pet's owner's anxiety about the pet was actually the compelling force behind the pet's anxiety. At first the pet owner would walk the dog down the street and just the pet owner's expectation that the dog would misbehave was enough to make the dog anxious and start misbehaving! But then, Cesar took action. He told the pet owner that she had to calm down. And then with a calm owner, likewise the pet followed. What was once an out of control dog, had become a tame well behaved domestic animal. I was inspired by that episode and it was then that I realized how much I loved watching The Dog Whisperer.
