Know that you don't know

Presumably above this picture everyone is very familiar (text in the picture from the network), in each person's reading each stage, will see the different scenery, also prompts us to read the significance.

In the first stage, it is possible to see just some illusion, the second stage, to begin to see the cruelty of reality, the third stage, to begin to see the beauty of the world.

Sometimes, about their own knowledge will have some confusion, some people summed up the knowledge of their own cognition is divided into four levels:

I don't know I don't know

Two, know that they do not know

Third, do not know that they know

Four, know that they know

The first stage, do not know that they do not know, may be because of information and resources, so that some aspects of information, such as their own to junior high school, have not touched the computer, naturally do not know the C and Java and other languages.

The second stage, know oneself do not know, enter the university, know the C,java, operating system and so on concept, but do not know its connotation. Actually found themselves in many aspects still in its first and second stages.

The third stage, do not know oneself know, but when you use, the nature will come out.

Stage four, know that you know, really understand their ability to understand their knowledge of the framework, know that they know later, it is easy to know that they do not know.

So, the more you know, the more you will find that you don't know.

Learn a lot, read a lot, and share it.
