I could not get through those three books but I get paid to program. My code is repetitive and shitty but I can produce a working web app as long as it doesn't have to support too many users, and it's fine.
My husband never read any books about formal programming and taught himself from those random "learn Java" or "learn python" books. He's a mathematician and programs to write simulations/solve equations, and he gets paid for it too.
If you can't get through those three books maybe you can't hope to be a computer scientist, fine. But you can certainly program, in the same way you don't have to be an English major to read or write.
