This book taught me how to be a person who cannot be replaced with robots. In this book, they told how to make a future. Now, the ability to find what we need is more important. However, before it was more important to solve that problem. Now, robots are more used for factories, and people who "solve the problem" are not needed. While there are robots that are doing people's work, a person who opened the future will never can be replaced with robots. In this book, it gives an "idra" that people will trap. one is pray's idra. This is about an idra that they believe too much about people who are better than you. For example, if your teacher said some wrong thing, a student will listen like they are saying the truth. Another type of idra is the market's idra. This name is named after the market because, at the market, many rumors are spread. People who believe that rumor is weak to this idra. For example, if you heard that person and that person looks like a friend, but hate each other, you might think it is true. 3rd type of idra is the cave's idra. This name has a cave in because you cannot see many things when you are in a cave. Cave's idra is about you believe one thing, and you think other people will believe like that. For example, if the person in a soccer club thinks "soccer is the best sports", that is okay, but if he says the same thing to a person in a basketball club or tennis club, that soccer club person is trapped by a cave's idra. And last, the 4th idra is called the body's idra. This idra is about the wrong thing that people believe and that wrong thing from your body's mistake. For example, you may think that will be people's face if there are 3 dots, 2 up and 1 down in an upside-down triangle. This is part of the Body's idra. I need to know how to check if that information is right. You need an "asking power". You, do not think people who are saying but think "maybe" that is wrong" about what that people are saying. You may have questions about your daily life. And adults, they don't think about that long, or maybe they even don't care. It is because they know too much. About many things. In their mind, they think that is a normal thing. However, they cannot find a bad point. So, they can't find a point to improve or how to improve too. For these reasons, a "new person" can be part of a people who opened a future. However, adults will not listen to you by only that. So, you have to make sure that adults will listen to you. To make adults listen to you, You can take all truth that is in the world, a truth about the wrong part. and make adults easier to listen to you, by using graphs like Florence Nightingale. If you cannot find a solution, you can change the "rule". You can change the rule, but you may not change the principle, a basic reason for why that rule is. If there is a wrong place, you can change the rule or frame of that genre and use another genre to make a new future of that genre. You can break a frame and change from the rule. Fransisco Bakon had a famous quote, "knowledge is power". Knowledge can change people. Knowledge can change "now" by power. Knowledge can make a new "future". Not giving up can be another important part of making the future. If you give up, you cannot make that future anymore. Don't through that dream away, even you feel like you are not on the path that that dream. You can make that dream come true even you are 50 or 60. How to make another Future? You can know from this book.
