This tip is for anyone learning any language, who's currently at a beginner or intermediate level. Many of you might already have realized it, but it came as sort of a revelation to me:
When learning a new language, don't think of that language as foreign. Think of it as normal.
I speak English natively and Spanish at an upper intermediate level. For years I thought of Spanish as a foreign language. It felt like I was learning something strange, because I didn't understand most of what I read or heard, and I couldn't speak well in it yet. But one day I decided to purposely switch my thinking and tell myself that Spanish was the normal language and English the weird one. So instead of asking "why is this English grammar concept so weird in Spanish?", I started asking "why is this Spanish grammar concept so weird in English?"
That simple change in my learning approach ended up making my learning much less mentally exhausting and much faster.
Perhaps this tip can be helpful for you for English (or whatever other language you're learning): don't think of the language you're learning as foreign, but 100% normal.
