Small changes can have big results.

I was writing postcards in batches of ten or more and breaking the batches down into steps it took me a few hours to write ten postcards and the batch nature of the operation although efficient was not giving me as much pleasure as writing the cards individually. So I changed to writing cards as a warm up exercise for the day and only writing five which I can get done fairly fast and now I am again enjoying writing postcards.

One small change has pyramided into a nice improvement in my routine. It is applied complexity.
