You said you were illiterate. I don't quite understand what level of illiteracy you are. If you can still type here and surf the Internet, then you are not really illiterate! First of all, give yourself some confidence! If you want to learn a language, I can recommend a website "Hujiang" to you. Com ",where you can find out what language you can learn and see if it suits you. I am also a student here now. Of course, there should be many other learning websites that may be suitable for you. I have no intention of advertising for Hujiang.com. Also, I'm learning to drive now. I don't think I need to know words before I can learn. Teachers teach orally and practice by themselves. I think the most important thing is whether you have perseverance. Many people are confused now (including me sometimes), but you won't feel confused if you set your learning goals. It doesn't matter whether you report to school or online (this is more suitable for office workers like me, after all, you have to survive before you can talk about development). The important thing is that the front is your goal, just move forward step by step towards your goal! Maybe you are still confused, such as what you can learn. Don't think so much. If you learn well, you will naturally find that your horizons have widened. Many times we think a lot, but in the end we have done nothing! Just like learning a language, learning English well requires years of hard work. There is no shortcut to learning!
You can't get the answer right away, so don't dwell on this question for too long. Try to think about what skills you want to learn according to your own interests (if you are not interested, just according to your own learning advantages), and then do your best. Temporary efforts are also for future development. Work hard!
