These are the things I wish I'd done when I could and maybe they could help you. 1. Read as many books as you can. You have a lot more time and energy now more than you will ever have and therefore it is important that you nurture yourself with books. They teach you a lot about life and that too, with out having to go through many things. It is also very important that you read many books to be a fluent speaker. Books help you organize your thoughts well making you a better speaker. 2. Listen to new songs, explore your taste in music. This is the time you are open-minded and so, make the best of it. Find your sound. 3. Watch all the classic movies. Movies can be very beautiful things if you know them well enough to pick the good ones out. 4.Learn to play an instrument or perhaps learn a new language. 5. Watch YouTube videos on matters you are interested in. (Check Jordan Peterson out, he has a good way of teaching people a lot of the things we tend to ignore. P.S He is very controversial) If you need books and movies and music recommendations, I might help you out a bit. Good luck!
