When I was a freshman in high school, I met a teacher who benefited my whole life. He was a middle-aged male teacher. He always gave students some good suggestions, he always developed a long-term plan, (like how to plan their own future How do colleges make new friends?) Since the first year of high school. He did train outstanding students one after another. Although sometimes the students (including me) feel that what he says is very verbose and annoying, after a period of time thinking about it, it will benefit a lot.
