I think people confuse the word “happiness” with the word “productivity.” People are definitely happier working from home. But at the end of the day, a desk is just a desk regardless of where it is. If you have a good work ethic, you’ll be productive whether you’re at home or in the office. People worked for decades in the office without any problems. Just have to get used to it again.
Many will not agree with this, but I think @1ved+1g3gkQZH hits the nail on the head.
