Tomorrow we are heading for a well-deserved and much needed holiday. Consequently it may well be several days before I have the opportunity to post again. It has only hit me during the past couple of days just how tired I have become, and almost overwhelmed by the number and variety of things to which I have had to attend. There is a concept in psychology of the “span of attention”. If I remember correctly back to my student days when I actually did courses in psychology, there is a limit to the number of things or activities to which we can attend before things begin to get out of control. (I believe it is six.) Frankly, I reckon that I have gone over that limit some time ago, and it is time to cut loose and take a break (even from art!). So I expect to be in “radio silence” for the next week. I look forward very much to being in touch again then.
