Patient's question:
NoDoctor's answer:
Concentration is a habit, and habits should be cultivated from a young age. The earlier you start, the better the results will be. In daily life, we often see such situations: parents buy their children many toys and books, but the children often flip through two pages of this book and two pages of that book, and the same goes for toys—they play with this one for a while, then switch to that one.
