Learning is an iterative process.
The so-called mind map is to package and summarize the knowledge to make it a picture, and the image is vividly stored in your brain.
Here is a simple example of how to learn: for example, VB
First, let's start from a macro perspective: first find a VB book (more classic), open the directory, and scan it all to see what VB has and what you have learned, what are new knowledge, and then contact your life? There is no new knowledge. They come from our life and can naturally find a connection from our life, we can establish a network, and we can easily turn "new" knowledge into our "old" knowledge, just like in the theory of eating, through the connection, it is easy to turn our "new" friends into our "old" friends.
Then, from the micro-woven network: when watching VB video, we need to export graph woven networks at any time, see the data type, make a small Map summary for it, see the array, and then make a small map, make a Map summary if it is difficult to understand or do not understand ...... After watching the entire VB video, let's make a general summary. At this time, we can link the summary to improve the integrity and integrity, the most important thing is that you can easily and quickly get a clear understanding of your ideas, and the overall summary will be completed soon. (Do not: the whole video will be summarized after reading it once, but the summary has been made for several days. This process is painful and slow)
Finally, the process of repetition: learning is a repetitive project. We can learn it once without any course. We must repeat it and understand it in repetition, it is not until the end.
Learning is a painful and happy process. Don't worry, don't relax, stick to your own ideas, stick to your own path, and go down step by step.
