I’m just back from a terrific stag do. We were badly hungover on Saturday morning but just about made it to the weekend’s activity which involved tripping up people in giant costumes, penguin sumo wrestling and climbing a rope on a slippery, soaped up bouncy castle (ending up arse over tit). Computer games and books are a poor substitute for the way we used to play in our youth.

Between the hijinks, pubs and clubs, my friend mentioned that his young son often becomes so engrossed in what he’s doing that when the time comes for him to go to the toilet he’ll carry on playing and ignore the consequences. Apparently this is common in boys. Imagine how fulfilling life would be if we took having fun that seriously. Imagine what we could achieve if we had the dedication necessary to wet ourselves rather than put down our pen, guitar or paintbrush. Perhaps this is taking personal productivity too far.
