To put it simply, today's middle-aged people may not have played their respective advantages in their time, but as long as they can work hard, or through their own labor and hands, that is their ability. Just like some examples around me, Wang Min next door is diligent and willing to work, and her knowledge and ability are not very high. However, when I interviewed him or talked with him, he always believed that as long as he was willing to work hard, he would certainly realize his value. Don't belittle yourself decisively, saying that you don't have a skill and can't accurately evaluate yourself and others.
First of all, as a new generation of middle-aged people, their thoughts and spirit should be greatly improved, instead of staying in the old feudalism. It is not the piano, chess, calligraphy and painting that can measure whether a person has a skill. In this society, as long as he is willing to use his own eyes to discover the beauty in life, or some achievements created by himself. Not all happiness depends on what you have learned, well, what others have not learned. It's the kind of happiness that others don't reflect on themselves. Every middle-aged person has his own skills. Believe in yourself and believe that you have the ability to surpass yourself, which is a kind of happiness and a manifestation of realizing the value of life.
