What to do with Downtime

I had an interesting chat with a client recently. We were discussing the movies and blogs on the Short Sharp Training website. He said that when he has downtime (waiting for the client to arrive/waiting for site visits) he goes onto the website to look for new blogs or movies to play. He has found that this turns his unproductive time into productive time, but not only that, it has made all his work more productive as he becomes more skilful at Vectorworks.
