A considered home is not decorated in a weekend. It is gathered, slowly, around how you actually live.
Resist the urge to fill a room all at once. Live in the empty for a while and let it tell you what it needs; the piece you choose after waiting is almost always the one you keep.
Buy for the long arc. One lamp you love beats three you settled for, and a home built this way never goes out of style because it was never chasing one. Slow is the aesthetic.
