Home decor woes

I don't think I've been so stressed since the SAT in high school! Decorating a house is so overwhelming and sometimes it is hard to know where to start! We bought a house last February and little by little decorated the major areas of the house: living room, master bedroom, formal dining room (which we turned into a game room with a pool table, bar and TV) and master bathroom. When my boyfriend started job searching, we put the decorating on hold because there was a possibility we would move, but now that we know we are staying here, it is time to stop staring at those poor, empty rooms back there. 
We decided to start with the guest bedroom, as his mom and little sister are coming to visit for his MBA graduation (YAY!). I don't know why, but I feel so much pressure to make this room even better than the master. I mean i love our bedroom, but when people come stay at the house, the guest room becomes their home away from home. I want it to be comfortable, stylish and most important within our budget :)  I have all these ideas floating around in my mind and I find myself grabbing everything I see that I like, even if they don't go together. Good thing my boyfriend was there to keep me in control. We bought the two key pieces today, the bed and a night stand and I want to now work around these two things. How overwhelming though to think of paint color, curtains, bedding and an overall a color scheme...oy vey. One day I'll be rich and hire an interior decorator, until then, here's to home decor magazines, Top Design, my crazy ideas and mixing it all together.
