It seems to me that language is the key to learning. Every field is as accessible as another if you learn the language. When you reach a new term or symbol write it down and look it up. Your memory will come with usage, talk to a friend or coworker about the things you learn even if they can’t offer you much in return, just saying it will help commit it to memory. Start a youtube channel and find people in the comments section to argue with about economics. The thrill of the argument should help you focus on particular elements to study so that you are prepared for the next argument and so on.
Bob Murphy’s Lessons for the young economist is a breezy and fun read with a very simple to understand glossary. If you are passionate about economics keep at it, you don’t even need to be good at it to be successful (just watch bloomberg or most of the Nobel winners). It is not easy to learn on your own but it is so much more gratifying when you do. Good luck.
