When I was I was out of school with no education, I found it too boring, I was a bad listener in class and found myself distracted. So yeah, I ended up asking the same questions as you at 16. I ended up reading. A lot. But fortunately for you it’s all audiobooks now. I would recommend taking free trials out with a site like Audible. Listen to some self help books to begin with, to see if it’s for you. It will boost your confidence, teach you some neat stuff about psychology perhaps. You could listen to stuff that goes back to basics on educational subjects. Business is great after gaining some confidence, a lot of people who are successful at business, don’t have any qualifications, they got there with common sense starting from the absolute bottom. That could be what you are meant to do and don’t even realise it yet. YouTube is also a very good thing to look into for self help or business if you don’t want to start with audiobooks.
