Why is it that there is less and less heartfelt joy when you grow up?

Why is it that there is less and less heartfelt joy when you grow up, I would say that is inevitable! As children, innocent, a candy, a toy, a praise, can make us happy all day! As children, we were carefree, and all the pressure was carried by adults! We don't know what it means to live a hard life, what it means to be responsible!

As we grow older, it seems like happiness is slowly disappearing around us, we're not happy with new clothes, we're not happy with holidays, why? First of all, because as we grow older, our demands are getting higher and higher, and not a toy, a piece of clothing can be satisfied! Maybe a trip abroad or an expensive gift will satisfy our desires! Secondly, when people grow up, they have to take up the corresponding responsibilities, to their families, to their friends, the burden is getting heavier and heavier, there is no way to be happy, for example, you read high school, then the pressure brought by the college entrance examination is far greater than some ordinary affairs that can make you happy, for example, if you are going to graduate from the university, then you will have to face the pressure of employment, and after graduating from the university to find a good job, you still have to find an object of the pressure, it's not easy to find an object to get married. It's hard to find an object to get married and have a child, then the pressure is even greater, responsible for their own small family at the same time, there are men and women of the elderly to support, the pressure is huge!

All in all, in short, the pressure and desire is with the growth of age and growth! And these two factors are the real reason for less and less heartfelt happiness!
