It is very possible, the best way to do this is to purchase the latest CCNA and CCNP material from Cisco, a Cisco CCNA/CCNP lab kit from Amazon and apply for a Junior Network Administrator job at your nearest regular business or government contractor. I would recommend going for routing and switching as this will give you a good base foundation of networking in general. If you buy a lab kit insure that the routers and switching equipment you get have K9 which allows strong AES/3DES encryption (SSH for example). https://www.amazon.com/s/?url=search-alias%3Daps&field-keywords=cisco+lab+kit https://www.amazon.com/s/?url=search-alias%3Daps&field-keywo... As you move through the certification process you will move more towards being at the professional level (understanding BGP, GRE tunnels, advanced routing, etc. at the internet level) instead of just switching and routing for a datacenter or building. The most important thing is to get hands on experience and actually understand how routing and switching works in detail. Nothing is more sad and embarrassing or worse than seeing someone with only book smarts and no practical knowledge due to no hands on real world experience. The longer you work at networking day to day on a job and at home using your home lab kit the better you will become. I started off learning networking at 15, and it has given me a wonderful foundation for everything else, especially understanding TCP/IP UDP and many of the various protocols in depth when doing software development, systems engineering, and various in-depth security work. Plus if you like it and want to do it for a career there is a ton of high paying jobs waiting for you as you gain more experience.
