The unfinished image can still record a good evening spent beside someone.

Not everything is worth judging by its product. A drawing abandoned halfway, a puzzle never completed, a recipe that failed, can each hold an evening in which two people sat near each other and talked easily, and that evening is the thing that actually happened. The object is only a receipt. Judging the evening by the object throws away most of what was good about it.

If you have something half done lying about, look at it and remember who was there. And consider starting something this week that you have no intention of finishing, purely for the company it creates.
