A famous quote by an old Zen Master Shunruy Suzuki says "in the beginner's mind there are many possibilities, in the experts there are a few." This saying makes an important distinction. It does not imply that we should remain beginners, nor does it refer to a naïve state of mind. The saying goes to point out that when we know a lot (or we think we know a lot, which is more often the case), we limit the possible choices - and therefore outcomes based on our discrimination. The necessity of keeping an open and non-discriminant state of mind about things lies not in needlessly analyzing every little detail, but in the ability to postpone a final discriminating decision until after all the relevant possibilities have been considered, and not before that time (which would eliminate from possibility all outcomes that you have not yet come to light or been thoroughly weighed.) It is a masterful quality not to react to things immediately based on preconceived ideas, even when the choice might seem obvious, but to practice reserve until you are certain of the reasons behind your actions, and in their validity.
