From the moment everyone comes to society, we begin to learn that we have all kinds of needs, from just eating and drinking in infancy to wanting to know everything in childhood. Then in childhood, I need to prove to adults or friends that I am great, and I can do many things well until adults need to live in this world by themselves, and finally I can enjoy my old age well. Prove that we have been working hard for our own needs. However, we suddenly found that "self-esteem, self-confidence and self-improvement" are in an extremely important position in every period of our lives. Without these when I was a child, it can almost be said that our childhood was basically gloomy. If I don't have these when I grow up, we will find that we have achieved nothing. If we are old without these, we will lose the courage to continue living, then self-esteem, self-confidence and self-improvement will become us.
