In my opinion it’s not enough by itself. I learn Chinese. I use many apps, have books and take group lessons. I occasionally go to meetups for learners too. In addition to all of that I try to expose myself to Chinese language via people IRL (family, neighbours etc) and from going to China itself.

If you want to learn a language properly you need to make it part of your daily life.

Man, I misread monolingoid and was like, holy shit people still say that? wtf!
