I've picked up a couple languages relatively easily and I 100% attribute it to the fact that I have no shame - zero

I will speak in my ugly, broken, American accent and do it til I improve. I didn't read about this technique in a book or anything, I simply mirrored what I saw kids do and IMO a big reason kids do well with picking up language (aside from all the physiological stuff) is that they actual speak it - they aren't concerned about whether it sounds like baby talk or not

A lot of advice feels trite and cliche, like keep trying, etc - but often times it takes repetition and hearing the message in many different ways before it sinks. As a tangent - this is the value i found in therapy too - a great therapist that was patient and consistent in their messaging day in and day out eventually led to some of what they said sinking in.
