Your favorite thing might be your skis and all the things that come with it, and if thats so, save a room close to the deck at the new home for all the toys.
The potential buyer needs to be able to see their things in the house, reflecting their taste, not yours and if a room is decorated in a theme of something they have no interest in, it can transform into a negative in their mind.
Keep all your rooms neutral and open to interpretation for a buyer. Neutral, but not bland is always a good choice. Use accessories such as flowers and pillows to enhance a room without turning it into something personal. Something that will draw the eye to features you want to highlight, like a standing mirror over a fireplace, or a beautiful piece of art on the mantle are always a crowd pleaser.
