Labor gives birth to ideas. （Jim Rohn）
In Japan, there is a saying, "It is like taking a rest for a bad idea. It means that no matter how much a person who is not good at what he or she does, he or she cannot come up with anything significant, so it is just like taking a break.
The same can be said for studying. The students who fail are absorbed in endless "bad ideas" such as "morning is better than night," "eating chocolate during breaks is good," "problem book A is better than problem book B," and "P cram school is better than S cram school.
If you have time for that, solve one math problem!
A student who has moved from another school.
I said to him, "Try this problem.”
He put the answer next to the problem and started to read it. That is called input, not output. Listening to an instructor's explanation or reading an explanation in a reference book is not called "solving.”
When I gave him a warning.
He said, "Are you saying that my way of studying is meaningless? This is what I was taught at my previous cram school!”
It was too much trouble, so I left him alone. If it were a school drama, I would have given him a pep talk and corrected his mistakes, but the reality is not so sweet. While I was correcting him, his rivals were moving far away from him, so he could never catch up with them. Those who do not sweat and try by themselves will never have a chance to pass the exam.
