Editing down to the essentials (but no further) can be applied to other things as well as poetry. Over the last few years I've been gradually reducing and simplifying my living space and personal possessions. I've done this not out of any ascetic philosophy, but because it makes me feel better - less encumbered. I enjoy the things I have more now than I did when they were lost in a sea of 'stuff'. It also has the advantage of helping me live within my means.
I've been interested to see at what point it felt right to stop. When is enough, enough? When would I reach the point at which disposing of anything else would be uncomfortable or limiting? The last thing to go was the microwave oven and I haven't missed it in the slightest. I'm now living in 32sq metres/345sq feet and it feels right. It's not as ingeniously designed as Gary Chang's famous example, but it suits me. I'm hoping it might also be a good place to settle down to writing again.
