Detours may take us a bit out of the way but they help us avoid all kinds of terribly dreary construction.
Creativity often has to do with taking detours. We see new things along the way. We make associations and then, if we're not too dismissive, we join them. To reject them is to be left mostly with just copying other's ideas and sometimes even posting pics of other people's work.
I looked at someones blog yesterday (this,now their latest website of several over the years) and saw some of my stuff there again and thought, 'oh well', I still think I've benefited more from having been the one who took the creative detours and came up with the ideas.
Originality will always bypass the more middle-of-the-road approach to doing things.
