We tend to live in a world of steadfast predictability. When that dinghy gets rocked, often we're unprepared to calm the waters, and end up being tossed overboard. Calm waters have a certain peacefulness, but not being adaptable when needed could lead to trouble. But a flat tire may be waiting for you later today. Having a Plan B is a must.
Predictability is nice, but fleeting.
It helps to be one step ahead of your own thinking. This can often lead to trouble though. Swimming too far ahead of the ship can cause you to swallow too much salt water.
