Why can t two things coexist in the same space at the same time?

Inspired by the Laws of Physics There is a law in physics that two objects cannot occupy the same space at the same time.

It seems that the same is true of the human heart, there is only one me in this world, and this one I can only exist in a certain place at a certain time, and there is a certain idea in my head, which means that if I choose to be happy now, then I have no sadness now; If I choose to be sad now, then I can't be happy; If I choose fear now, then I don't have the time and energy to find a solution; If I choose to face it now, then I don't have the time and energy to experience the fear. In the Ming paragraph, people say, "I feel hopeless", then when you live in hopelessness, all your thoughts are occupied by hopelessness, even if you are surrounded by discontented hopes, you can't see them; People say:

I feel that there is no love", then when the sense of lack is occupied, the mind is all I don't have, and there is no time and space to see the love around me.

One yin and one yang is the Tao, we say that things do not exist alone, everything has its other side. Is it true to say that there is no hope? In other words, is "I have hope" also true?

Is it true that I have no love"? So is the other side of it, "I have love", also true? There is indeed an uncontrollable side in this world, and in turn, this world also has its controllable side, which is also the "Tao of one yin and one yang", if there is indeed something beyond your control, then there must be something within your control, and what is it in your life?

For example, if you want your child to study well, but the child just doesn't learn, you are not a child, even if you can use various methods to let the child stay in front of the learning table and sit for a few hours, you still can't control the child's learning effect, because the head and thoughts are growing on the child's own body, and this matter is uncontrollable. Then, in turn, what is controllable in the uncontrollable matter of the child's learning? For example, children themselves are also stressed when they do not study well, so we can control our emotions and help them when they need it, rather than making them more stressed. For example, learning communication, learning psychology, better understanding of children, better motivation of children, etc., these are all things we can do, and they are all controllable.

At the same time, two objects can't occupy a space at the same time, so when your thinking is on how to do controllable things, how to solve what I can do, you don't have the time and space to focus on the child's shortcomings, to focus on the things you can't change at all, things will naturally develop in the direction of Huaiye's good.

Ladies and gentlemen, what other things do you think can be solved by two objects that cannot occupy a space at the same time, and the saying of one yin and one yang?
