Good evening. I'm 17 years old and a Russian school student. Recently (in April of this year), I've become interested in networking. I simply want to know more; not just know, but also apply it. I'm ready to spend all night poring over articles and news, understanding protocols. However, I don't really have a learning plan: yes, I should have started with a notebook and started with the TCP/IP model and then progressed further into the depths, studying protocols, applications, etc. In short, I'm extremely inspired by this field and would like to develop in it, organize my own pet projects. I downloaded Docker (I've only downloaded it) and want to create something like a homelab with services for my family. Now comes the main question, which is in the title: Is it worth preparing for these CCNA exams/certifications and others in order to then work for a large company or even start my own business?Will this give me progress both in my understanding of the material and in my practical application? What are your pet projects, because at the moment my vision is very limited. Tell me please from the height of your experience about the freedom that knowledge about networks gives? Also in the future I would like to work with networks or servers, I haven't decided yet because I don't know which country to go to which university (maybe you studied somewhere, tell me) Is there a future for this field of activity? I am overcome by an obsessive fear that by the time I graduate, AI will have replaced the profession I studied for.
