To be fair perhaps you need to consider more what you could give a parrot. A dog can be trained to follow you around and possibly a cat, but a parrot tends to be it's own person and may take more than it gives.
Also they tend to choose their owners more successfully than the other way round. You will need patience, empathy, cash, time each day, and the ability to be let down at times and still love your bird even when blood pours. Syd moved in with me having chosen me as a house mate. He's little but still a big challenge and patience is my middle name but he is still more challenge than any dog etc I have ever had.
My first advice is don't rush into it. Take a good look around at all sorts of birds. If there is somewhere where you can volunteer so that your have hands on experience do that for a while so you can get the feel for them. You may find the perfect bird who thinks you are perfect too. Read, read, read and ask questions and make sure you have a contingency fund for initial set up and vet checks.
Having said that - they are brilliant and worth the trouble. You see I'm a convert! You have made the first good decision by arriving here. Good luck.
