Steal someone else's by asking your paint store for the top 10 colors purchased by their customers. There's a very good chance that one of them will be the ideal color for your project. This also works for carpet, tile, hardwood, etc.
Just the opposite. The more you call attention to the ceiling, the larger and more interesting the room can look. Changing the color of a ceiling forces the eye upwards so that walls, windows, and objects in the room are fully noticed.
It's a myth to think you have to use special paint to create chalkboard space on a wall. Chalk will write on any painted surface (assuming latex paint was used, that is). The darker the paint color, the better the writing will appear. And it washes off with water.
Start with the rug (if one is to be included), then work your way up (sofa, chairs, other upholstered pieces, tables, etc.). Choose window treatments next, then lighting and small items (lamps, accessories, artwork). Paint color should come last.
Unfortunately, yes. Although it can be done in a way that is more artistic and less dated. Try papering just one wall, or use it as an inset for panels made from trimwork. You can also use wallpaper as a covering for a wooden cornice board, resulting in a custom window topper that coordinates with other elements in the room. Keep in mind, a little goes a long way.
The kitchen. I'm finally learning to cook, and I've discovered this is the best room to do that in.
A remote-controlled dumbwaiter.

Forget choosing individual paint colors for every room. Pick one you love and paint every room the same: Lighting will make each room appear to be a different color anyway. My current go-to shade: Ben Moore's Everlasting.
Lately, I've been visiting gourmet food stores and French restaurants. The ambience is off-the-charts gorgeous, and if you have a spare $35, you come home with a quart of the best chicken salad you've ever tasted.
I acquired a nail gun last year and have spent considerable hours wondering how I ever lived without it.
Forgetting to recharge my nail gun battery.
Never underestimate the power of caulk. It's cheap and covers many flaws. If it was safe, I'd use it as makeup.
