I learned about bikes by trial and (sometimes) by error, ever since I was a kid. My father was a car mechanic. I borrowed his tools (mainly wrenches, screw drivers and pliers); which was far from the special tools I really needed.

30 Years ago bikes used to be less complicated than they are today. In those days we had no internet nor Google, so we had to find out by ourselves. I cannot remember any pro bike mechanic helping me out when I was in trouble. Fortunately, my dad was my guardian angel.
