[BLANK_AUDIO] I remember 12, 40 years ago I was in a training with consultants. And, after the course. One of them came to me and told me, look, this is really what I want to do. Help people to think more creatively, etcetera. I said, fine. This is my role, to anchorage people to do the same kind of job I'm doing. And I told her, it was a woman, I told her. Go somewhere, try and I will sit in the back. And you'll have feedback afterwards. That's what I did. I went to the place and she has her presentation. It was not good at all. I was, a bit in a difficult position. Because I, asked myself what happened? She had energy. She wanted to and it was good, not, not good. And suddenly I understood. She was not good because she tried to do what I did. She tried to imitate, the way I do this job. Not a good way. If you want to become a good accountant for example, you have to imitate another good accountant, definitely. In this, in this job, no. You have to share the passion. You have to share the energy. But you have to be yourself, yourself. And I had a good idea. I asked her, tell me what is your passion? And she answered, architecture. Fine. And then I told her, I'm going to come back. I'm going to listen to you a second time. But on the screen, I only want to see buildings. And that's what happened. It was brilliant. A combination of ugly buildings, new buildings. Old building, changed buildings. [SOUND]. It was brilliant. And to me, it's another important souvenir. It means, creativity is not about knowledge. Like accountants of computer science, you have to learn from somebody. No, absolutely not. There are some concepts and we cover most of them during the six lectures. It's much more about passion. So, if you want to do something like that. Select the passion here, you have inside of you. And build everything. If you have a passion for music, go to music. You have a passion for painting, go to painting. There are many, many ways to deliver the same, the same message. And you will be definitely much better building on what you are. That's the way. And now, I come to an end. So, I will do what I just told you. I will build on my passion. I have a passion for philosophy of science. You have noticed before. There's so many, many anecdotes. Useful. So, let me give another one. We met Edison, I think, during lecture one. About this incredible paradigm shift about the light bulb. But Edison is such rich personality, you can learn more out of him. And if the light bulb was definitely a beautiful eureka. He also had some great carambas. He made big mistakes. Even genius are making mistakes. And one of the most incredible mistake he made, he fought against the alternative current. Strange. Such a brilliant engineer, how is it possible to make such a mistake? It is possible, because the mechanic is the same. And sometimes the challenge, it's not to survive the failure. Sometimes it's to survive success. And that was the case of Edison. He had so many successes at the beginning of his life. He patented the [UNKNOWN], telegraph and things like. All of them in direct current. So at the end of the 19 century, when this idea of alternative current slowly came. He fought against. And at that time, they want to organize the electricity throughout New York City. And his competitor at that time was Westinghouse. Who used alternative current. It was a big war, and a big mistake. So at the same time you had great eurekas and great carambas. But more, more than that, he was a man with convictions, with beliefs. And two of them are, to me, really the most important one. If you want to be good in this, on this topic, creativity, etcetera. You need one, never stop thinking. Second, enjoy. Enjoy thinking. The real joy of thinking together. And those are my beliefs too. Maybe just to leave you a last anecdote about Edison, that covers both aspect. Non-stop and enjoy thinking. He was, he lived, I think, until 84 years old. And at the end of his life he delivers speeches. He was a star, a super star. Key note speaker, invited everywhere. And one of those evenings there was a question time. And after, this, this, talk about his life. One woman raised her hands, and asked Monsieur Edison. Thousand inventions. It's incredible. I have two questions for you, she said. First question, which is your very first invention? And Edison said, ooh la la. That is long time ago, long time ago. Now I remember, I was in a village. And the neighbors had a nice daughter. So I want to go out with this daughter. And in order to organize that, I fix something in the oil lamp of the father. I did something. And suddenly, the, the lamp, the light was brighter, less smoke. And, the father was so happy. I had the permission to go out with the daughter. The woman was, yes, of course, completely overwhelmed by, by the, by Edison. And then she, hey. I have a second question. Which is your very last invention, she asked? And Edison then looked at the woman and he answered. My very last invention, the story I just told you. We have reached our final destination. No. This is not definitely not a final destination. I have to leave you, of course. And I thank you very much for having made this journey with me for, throughout those, those lectures. But, I really hope that this is not a final destination at all. I wish this is a starting point for you. My job is not about what you should think. It's about how we think. And in the end, I don't have food to offer. My passion is to make people hungry. I wish you bon apetit.
