What is your biggest challenge to you today?. Well, I'm an engineer, and in this field I like it the most for most of my years in this position. In the mid-90s I studied the world from a very early age, and in that time I think about the various elements in my life: history, art, culture, and the everyday problems that need solving. I started researching things that might make me feel better, because I was more knowledgeable. But in this field there is a lot of stuff that is very hard for the average person to study, so you also have to think about ways to improve your understanding of the world. My learning was about the world from an early age. As a physicist I think about scientific methods, and even about some techniques. So I would like to focus on a scientific method rather than a technological one, because I think that the method's more interesting to me if it really serves a good change in the world. When I work on something, I think that it's important that certain things are used the most well, and that something is used as quickly as possible.
