"There are three avenues of opportunity: events, trends, and conditions. When opportunities occur through events but you are unable to respond, you are not smart. When opportunities become active through a trend and yet you cannot make plans, you are not wise. When opportunities emerge through conditions but you cannot act on them, you are not bold. Those skilled in generalship always achieve their victories by taking advantage of opportunities."
Zhuge Liang (circa 200 AD, The Way of the General)
