My introduction in the world of cryptography

Hello everyone!
My name is Othmane, I am 16 years old, I am a Moroccan high school student and I am passionate about all that touches the field of high tech, but also about the lego universe. I saw in this community not only the opportunity of sharing my creations, but also to discover a domain that is still foreign to me, cryptography. At the very beginning, when I learned about this technology through my cousin's ticket, I thought my age would hinder my learning, but after some research I discovered that several high school students have succeed in this area, Which motivated me to invest myself. I have a great desire to learn more about this, which is very important to me as it will change our society and our way of thinking. All your advice is welcome because I really don’t know where to start :)
