We often use "unclear" to describe whether a person's mind is regular. This is very vivid. For example, many silk threads are intertwined in one place. If you can pick them up and they are not entangled with each other, it will be easy. You can knit them one by one. I like making handcrafts and knitting bracelets, so I need to hold the silk thread clearly. This is the basic skill.

So how can we effectively organize what we have learned? Mind mapping is an effective method.

For example, we all have emotions and everyone has emotions. Let us discuss a lot, such as happiness, pain, sadness, anger, sadness, boredom, regret, helplessness, fear and so on. In fact, many can be summarized into several parts. Starting from the basic emotions, nothing else belongs.

We often say "joys and sorrows", but the basic emotion is "joys and sorrows". If we remember four emotions, the other emotions are branches and leaves. Try to draw a mind map.

On the basis of these four basic emotions, many kinds may be derived, forming a compound form and forming a high-level emotion. Such as disgust and pleasure related to feeling and perception, pride, inferiority, self-confidence, shame, guilt and regret related to self-evaluation, and love, resentment, envy and jealousy related to evaluating others.

These derived relationships can continue to be represented by mind maps, so that you won't feel at a loss.
