Why deeper transformation takes a long time

I've lived in this rectory for almost six years. When I moved in it was freshly painted. Some of the colors are lovely even today. But some were too dark. And the sea foam green in two of the bathrooms reminded me of doctor's offices. So this summer I decided to use some of my vacation time to repaint the rooms.

Five rooms in five days, that's what I did. The sixth day I put everything back in order. When it was all done I felt an immense sense of satisfaction. The look is new and calming.

Now I ask you, when, ever, does a transformation happen like this? With just a few days of work—hard, exhausting work, but still—everything is different. Not only different, but exceedingly, satisfyingly different.
