Here is some advice Professor Gustavsson gave a student who was deciding where to position a tree in a landscape design. 'Honour it with its own space'.
I think the principle applies in the home. You might like to experiment with the idea. Choose an object which is really special to you and clear off a shelf, a table or a worktop and place just that one thing in the space and live with it for a few days.... For me it creates a feeling of calm, and a fuller appreciation of the bowl or jug of flowers or whatever item is chosen.
You might try it in each room of the house.
Take a before and an after picture! It helps you to see it more objectively.
