I have this simple tip for creating a more relaxed atmosphere at office. Surround yourself with images that make you feel happy and relaxed. They could be pictures of your kids, maybe your girlfriend or boyfriend, even your dog - just anything that gives you happiness. Apart from pictures, I like to put up some quotations, or a funny sentence around my workspace. So anytime the deadline is approaching, or the boss is being mean, or you have got annoying co-workers, just look up and see things and people that are really important to you. They would make the situation seem not so bad. Try it for yourself!
