We often leave it for last, but ultimately it should be one of the first places we take care of. We want to create a place where we can rest and feel replenished. So you want to take care of the bedroom, kitchen, and living or family room first. I had a garage sale and sold a bunch of my husband's bachelor things when I was trying to clear out some clutter. Now I've learned to communicate better.
Marriage is about compromise.
You need to recognize that when you are married, and if you have a family, you aren't just decorating for one person. You need to listen to each other. For example, my husband had a special painting of his grandparents that I stuck in a closet for years because I didn't want to hang it. Finally, God convicted me that I was decorating for me, not for us. So I reframed it and gave it to him for Christmas.
