Acquiring a parrot will almost certainly require some degree of change in your lifestyle. Here a just a few examples.
	You know now that the care and maintenance of a pet parrot is going to require a considerable financial commitment on your part. Every dollar you spend on your parrot is one dollar less you will have for movies, meals out, or the occasional brewski with the gang. Is a parrot worth cutting back on any of that? No cheating, now. Once you acquire it, you have a moral obligation to your parrot to insure it receives the best possible feeding and care. On a slightly different twist, if we are talking a dollar less for rent, groceries, healthcare, bills, or family then don't even think about acquiring a parrot! To do so would be grossly irresponsible to those depending on you, and to the bird you can't afford.
	The care and maintenance of a pet parrot is going to require a lot of your time. This is time you will no longer have to hang out with the gang, study, or get your honey-do list pared down. Think about this carefully. If you can't spare this time on a daily basis for the next 20 - 80 years, then you don't have the time for a parrot as a pet.
	A parrot, it's cage, and accessories are going to require a considerable amount of space in your home (don't even think about an unheated garage or unoccupied basement!). Remember, you are replacing 900 square miles of rainforest with a few cubic feet of enclosed space so you owe it to your bird to get the largest cage you can possibly afford. Then there is the t-stand and the play-gym. Where are these going to fit? What about storage for food, spare toys, travel cage, hygiene and first-aid supplies? Parrots themselves take up little room, but the equipment, accessories, and supplies to keep them health and happy can take up significant space. If your home is like mine, every nook and cranny is crammed to capacity. Obviously, something has to go or you may have to build on or move to a bigger home. Are you willing to give up the space required to have a parrot? Do you have the space to start with? How about everyone else in your home? Think long and hard about this before you buy a parrot because 20 - 80 years is a long time to be tripping over and working around your parrot's stuff.
	One of the most important things a parrot will need from you is to feel safe and secure in it's new home. Unless you are a recluse, this usually means lots of new rules. Children are generally attracted to parrots like magnets, but many parrots simply don't like children. Children are also more seriously injuried by a parrot bite, so there must be firm rules established if children are present in the home for the safety of children and the parrot. Friends are another issue. You would be surprised what some people feel they have a "right" to do to your parrot when visiting your home. Relatives can be the worst of the lot! You must establish rules for visitors and firmly enforce them. They may not like this, but don't be afraid to remind them that your parrot is a member of your family and they are not. It's also a good idea to share responsibilites for the care of the parrot, as this helps to prevent the parrot from over-bonding to any one individual. Rules will have to be established about who is responsible for what duty an then strictly enforced.
This list only scratches the surface. Exactly how a parrot will influence you lifestyle depends entirely on your individual lifestyle. The one thing you can count on is that your life will change. The best thing you can do is to seek out parrot owners (parrot chat forums on the web are a great place to start) and talk to them about how parrots have changed their lives. You have my assurance that you will get an ear-full. You will hear the good stuff and the bad stuff. However, it is much better to find out that owning a parrot will change your life in unacceptable ways before you learn it the hard way.
