Shutdown your messaging apps (or even your phone) for a few hours every evening. You don’t have to wait for a global shutdown to happen.
Go read a book, spend time with family, or just sit idle and be bored. Give your mind to work its magic in the ‘diffused mode’ of learning (read more about this in ‘A Mind For Numbers’) where it makes cross-region mental connections.
Your work will improve when you stop worrying about it every waking moment.
