different goals and different way of tackling problems is maybe why people struggle with Linux? like someone only knowing Western languages taking up Chinese , where they approached the communication issue a bit differently. apple and Microsoft wanted a user friendly experience that everyone in the family can use a computer.

how Linux works is a good book if you want to learn more indepth. also something like Linux from scratch. not only will you learn a lot about Linux, but operating system design, networking, storage, etc. doing this will legit give you a better foundation than quite a few IT technicians.
