Thinking about decluttering a whole house is overwhelming, so it’s best to begin with a clear focus. Marie Kondo, the queen of decluttering, advises you work by category, rather than room and that you tackle them in the following order: clothes, books, papers, miscellaneous (we’ll come back this!) and sentimental. Don’t be too harsh in your first round, as being too extreme might cause you to panic and rush out to the stores to fill the gap.
