If you're thinking about getting a house, start actively paying attention to the things you like about houses you visit. If a house seems inviting, figure out what makes it that way. Maybe it's all decor, but maybe it's windows, a fireplace, or some other aspect of the house itself. Start a list of features that you would like. My must-haves were ranch style, garage, basement, three bedrooms. My would-likes were hardwoods, attached garage, close to the bus line, attic space, breakfast nook. You'll find out, after you move into a house, that there are many things you hadn't anticipated, both good and bad. (For example, I didn't realize that my bathroom didn't have an electrical outlet until one of my friends stayed with me for a while. I don't use a hairdryer or anything like that, and just never noticed. For someone who did, this would have been a pretty big annoyance. We ended up running an extension cord over from one of the bedrooms.)
I didn't think about windows at ALL, but this is one of the things that people mention when they visit my house. I lucked into a house with a lot of windows, and I've found that one of my favorite things about having a house is being able to sit on the couch with a cup of coffee (or tea, or hot chocolate) in the winter, watching the snow through the picture window in my living room.
