One of the biggest changes you need to make if you want to stop hating Mondays is to stop complaining about the day with your co-workers. You may think you’re creating some solidarity with those in your office, but really all you’re doing is perpetuating misery. Granted, for some of us, even a great Monday is still worse than all the other days of the week, but no matter what you do, Mondays will still be there, so you may as well make them as pleasant as possible.
