I am a person who thinks half slower than ordinary people, and looks a little dull to others. After graduation, IT was really difficult to make a living in this major, so I started to study IT by myself and spent about eight months to study by myself.

After self-study, I probably used A4 paper, evernote, mind map, CSDN and Markdown to write down some learning notes and problems. Change the carrier of writing all the way, A4 paper is convenient to write, but not conducive to review, modify and spread, and sometimes will be lost. Evernote these problems are solved, but it is not conducive to search, when looking for information, you have to look through all the files. Later, I learned “mind mapping” at work, which allowed me to do more divergent thinking. Many complex problems, thinking guide pictures, suddenly enlightened. Moreover, mind mapping can record the framework of knowledge and build its own knowledge tree.

After we acquire knowledge from books, work and life, we should insert the corresponding knowledge into the “knowledge tree” in our brain, which is suitable for us to construct with knowledge mapping. When we encounter problems in work and life, it is ok to find the corresponding knowledge in the “knowledge tree”. If there is no knowledge in the “knowledge tree”, we can insert the knowledge used in the problem after learning the “knowledge tree”.

However, if the problem we encounter is more complex, “mind map” can only describe a general, then we need to use something to refine the knowledge point, to help us clear the knowledge point.

At this point, we can clear up this knowledge point by writing an article.

Why does writing an essay help clarify the point? At present, I think, my mind is slow, when learning knowledge, knowledge has been inserted into the “knowledge tree”, this knowledge point is so difficult, I do not want to think to understand. Writing articles forces us to put out the knowledge we put into the knowledge tree. If you want to output, you must output the knowledge of the “knowledge tree” to the “article” through thinking.

That’s why I started writing.
