I have a good classical music in place to listen to when I am trading cryptocurrency, with that I can trade without much stress. Also ,I get some green tea on my table to take to refresh myself.
One should take some break and move away and do what they like it. Go down and enjoy the nature's beauty, read something, listen music or watch TV. Play some sport or do drawing etc. This will help you to keep your mind fresh and you can be back with more better positive vibes to work on.
