You can look up youtube videos all day and read books on how to fix cars (all whilst working on yours only)
Or attend a school where you will be taught by experts in the field, have access to all the tools and resources, as well as a plethora of automobiles to work around? All this, in addition to the many connections and relationships you will make with those in the industry?
So uh, yeah. You're a giant buffoon.
Why are you talking about cars?
Also I stated in the OP that I'd be better off actually being taught something rather than trying to work it out on my own, plus the degree at the end of it is worth something.
So uh, yeah. You're the giant buffoon.
