Solid colors through the home can get boring real quick. Whimsical patterns like polka dots can add a visual interests and contrast to a minimalist home.
The easies way to combine patterns in a space is to combine it with a white background and/or complimentary neutral furniture. In this way you're allowing your pattern furniture to be the center of attention. Buying furniture in pairs also allows symmetry and a balance in the space if you can swing it.
Add a simple gallery wall above with floating frames of inspirational quotes in a tasteful way to remind you to kick butt every day. Keeping it minimal so it doesn't clash with the polka dots.
