This certainly resonates with me. In my professional environment I use my third language, and, while it takes more thought to express myself, I am more assertive and open simply because the words carry "less" weight to me. Another positive side is that I'm more difficult to offend or upset.

Sometimes I translate in my head what I just said back to my native language and realise that chances are I wouldn't have said it if I had to actually say it in my native language.

It's weird. It's also not something I think about on a daily basis. It's simply how it works.
