Routine design When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art. The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.

Babble and Prune For those who read and listen much more than they speak (guilty), an overly-strict Prune filter is applied to their writing; when these people go to write something of their own, their minds don’t produce thoughts nearly as “coherent, witty or wise as their hyper-developed Prune filter is used to processing”. Hence, my dilemma and an opportunity to break out of this trap. I recognised that if I attempted to write at the quality I was used to reading at, first time every time, my brain would promptly grind to a halt—like trying to brainstorm with a group that laughs at your suggestions. writingcreativity
