The “100 no. 3” project on the official Peace Matayoshi [vortex] channel, a Youtube channel featuring comedian Peace Matayoshi, is very interesting. The content of the project is as follows: First, a theme is decided. Then, the contents of the project is to decide one theme at the beginning, and to line up 100 contents that correspond to the theme. For example, there is a theme of “things that made me an adult. From there, the project is like an association game in which the participants associate words and memories that correspond to this theme. Over the course of a day, you would narrow down this list of related words to 100. Then, finally, he would select the BEST 3 from the 100 items he had come up with and tell the listeners about the 3 episodes. We thought that planning this YouTube content would be similar to a mind map. This idea of mind mapping refers to the free flow of thoughts, ideas and information, branching off from a central concept. This way of thinking is a very important way to think and is a great way to hone one’s creativity. It can also deepen one’s life memories and thoughts; consider that it is very difficult to narrow down to 100 relevant words for a single item. It is very interesting to watch the performers rack their brains for a day about that difficult task.
