Most learning now is “self-taught” education at home by internet exploration.
You will have no problems finding fun ways to learn.
Academic experts have broken down the most complicated subjects into bite sized doses of knowledge with pictures, diagrams, and videos to go along with the content they are explaining. Don’t be surprised if you find a 16 year old talking about US Naval nuclear propulsion on advanced submarines with incredible definition on the subject. I saw a teenager who spoke over 20 languages on YouTube; even a pre-teen software programming prodigy. We can see anything we want to learn about while looking up anything or any word we don’t understand. This is precisely the way I learned about HVAC. Learning about the coils, ductwork, refrigerant, compressors, the fan, capacitors, boilers, and radiators was frustrating. Since I’m used to learning what my imagination is curious about, it has become difficult to absorb boring textbook style information. When I started reading funny stories and horror stories about the experiences of HVAC technicians I immediately began comprehending the central heating system, follow by the air conditioner process. Entertainment learning can be so powerful when trying to personalize learning. One HVAC technician on a well known website mentioned going down a “trapdoor” inside a trailer to do an HVAC replacement estimate. He ended up crawling over bones to discover a 12×14 duct run leading to an over sized 20×20 coil. In another story he posted about a furnace in a basement; apparently the entire room, furnace, and water heater were all covered in a thick layer of baby powder.
