What are the eight-character old idioms about teachers' expectations of students?

1. Some people just listen to what others say and then make random comments. I want to say to these people, "hearing is empty, seeing is believing."

2. Every time I get a result, the teacher will use "take a step further." This eight-character idiom encourages me.

There is another problem, no one is perfect without money.

The teacher often tells us: "Only by laying a good foundation can we learn better." This is the so-called "a journey of a thousand miles begins with a single step."
