By creating a relaxed environment. I know what you mean. My significant other always throws things, kicks objects and all this causes is shattered pieces and broken toes. So I found out his favorite colors that soothe him. I pained the living room his favorite mint green, bought bright blue paddings for the wooden chairs, found green colored kitchen utensils, hung some pictures of trees and frisbee golfers, went to Walmart and bought a tiedye shower curtain, blue matching towels, and we grill at least once a week all to calm him down. Now we only have a broken toe or shattered pieces twice a year instead of twice a month.
