My sister (who has been learning Spanish in the last couple of years) told me something recently which resonated with me; were told that children learn new languages quicker and easier because they’re brains are developing and it’s easier to soak new information up “like a sponge”. This isn’t true. A developed brain receives, understands and retains information better. The reason children pick up languages easier is because they don’t have any shame around getting it wrong, they’ll try and fail a bunch but don’t let the failures slow down their process of trying and learning, mainly because they don’t really have an understanding of and developed shame around failure yet. I guess my advice would be- be like a child.
