What is the "Unsolved Puzzle"
In the process of your growth and progress, you should encounter some doubts that you could not solve at that time. Record them here and answer them later. Sometimes, self-questioning and self-answering can make you more aware of your progress.
When you are not satisfied with the last answer, you can add or delete it indefinitely below.
Therefore, "Unsolved Puzzle" is a recording tool used to examine self-growth in the future.
