When I was a small child, I cried because of the things that were not mine due to ignorance. But from the stage of being able to understand, it is necessary to pay attention to find things that have not been done, and prepare plans. I have seen elderly people in my neighborhood still complaining about what they lost. This wastes valuable time that could have been spent collecting something. I definitely pay attention to the questions of whether there is something that I want to acquire, whether it will be of more value that I should own it in the future, and whether I can own it, and I plan my future activities according to the answers I get.
