This problem cannot be generalized. I think it is necessary to educate children, when they encounter major problems and fundamental interests, whether they should suffer losses or not, and earn what they earn, and there should be no ambiguity. For example, we must not suffer losses in major events such as further education, college entrance examination, postgraduate entrance examination and promotion.

It doesn't matter if it's a trivial matter, but it can also leave a good impression on others. For example, when you live on campus, take out the garbage from the dormitory and buy bottled water for the dormitory without other students paying for it.

Bottom line: small things are not afraid of losses, big things can't suffer, and of course they won't suffer.
