Language Modes or Monolingual Focus: What's Your Approach?

I’ve always been curious how other polyglots handle switching between languages for different tasks. Personally, I find that sticking to one language for focused work like analyzing economic data helps me avoid mental clutter. But when I’m composing music or just relaxing, I enjoy letting my mind drift between languages. Does anyone else experience this, or do you prefer to keep things strictly monolingual for certain activities? I’d love to hear what works for you!
