Don't be afraid of color. Push yourself to incorporate colors that are outside of your comfort zone. Burnt orange, chocolate brown, green and grays are great options.
Make an effort to stay organized. Ikea has baskets in different sizes that work well for storing everything from jewelry to makeup.
Keep personal photos and decorative pillows to a minimum. These should be used as accents throughout a space and be sure to only showcase those that you truly love.
Keep TVs enclosed, if possible. An armoire is the perfect way to keep a TV set and all of its unsightly wires out of view.
