What is the essence of having no opinion?

? ? People who have no opinions lack the understanding of giving up and getting. Everything has two sides, giving up is getting. Giving up and getting is the contradiction of unity of opposites. Everything is willing to give up. You have to give up before you can get what you get. Being willing is a kind of understanding, but also a kind of wisdom and a realm of life. People who have no opinions lack understanding of giving up and getting, and don't know what to choose before giving up. ?
