A motivational speaker who wanted to warn about how bad habits or vices start out small told the following illustration. In the old days of bridge building they would first tie a thin thread to a kite and then fly it to the other side of the river. Once it landed there they tied a slightly thicker string to the thread and pulled it back to the other shore. This went on many more times until finally a strong steel cable could be pulled across the river, the first part of the bridge.
I am reminded of that story when crossing one of the numerous suspension bridges in Taiwan’s mountainous regions where many of its indigenous people live. These bridges look rather flimsy and sway up and down and back and forth when crossing, but they are actually quite strong and the local people drive their motorcycles across them without hesitation.
