For me, setting goal of perfect fluency was recipie for failure. Every time I didn't speak perfectly I beat myself up, which made things worse for my anxiety. This was not good for anticipating if my conversation will go well or not, and I'd lose sleep over it. So now, I simply aim to give my best effort ... regardless of the outcome. i commend myself for the effort, not for the outcome. This has IMMENSELY helped with my mental health and outlook on life. Nothink fazes me anymore, because everytime I try to communicate, I know I gave it my best, that THAT's what really matters.
