How often do we say to someone: why are you like a child !? And we put a reproach into this phrase. Childhood has many aspects, but some of them are not worth losing as you grow up. In some ways, we can learn from children and gain invaluable experience for ourselves.
Adults, in comparison with children, do not know how to be surprised at all, or they do it very rarely. Whereas for a small child absolutely everything is new and surprising. The baby accepts any experience with joy, absorbing it like a sponge. The child is equally joyful and interesting to wash the dishes, go to a new playground or play with an unfamiliar toy. We are looking for something special as a reason for joy, forgetting about the simple things that surround us all the time.
Children are spontaneous in expressing their feelings. If a child is sad, he is sad; if it's fun, he smiles. It seems that everything is simple. But as we get older, between feeling and expressing it, we start to think too much. And how will it look from the outside? Are there any reasons for joy? We either block the expression of emotion altogether ("now is not the time and place"), or we often express something completely different from what we feel. So, trying to save face, we lose touch with our inner world, we stop understanding ourselves. Thinking and feeling are completely different things. We, like children, need to allow ourselves to experience any emotion. And to think about how to adequately express them in their behavior. But just to smile from a good mood, after all, no thought is required.
These are just two aspects in which we can learn from children. Looking at your child, you can probably see something else. But even with these two things as an example, it can be said that "being like a child" is sometimes not so bad. It is not always necessary to just educate and raise children, you can also learn from them.
