I was building kits by the time i was 8. About that time i could usually reassemble what i took apart, and it worked, usually correctly. Had ordinary soldering, wiring, and assembly down pat by age 10, knew color codes and started learning typographically marked at the time. Pretty near 50 years ago. About age 12 i was reading and understanding college electrical engineering texts. Much later i was a working engineer with 10 years experience doing decent stuff while finishing the BSEE. I started young and am multi educated. And i don't give a rat how any of you got where you are. I am here to discuss electrical engineering.
