4. Show Appreciation
When people appreciate your efforts you feel good. You get this feeling of satisfaction to be recognized for all your hard work. The same applies when you are appreciating somebody too. When you tell your co-workers what a nice job they did, it makes them smile, it brings happiness. And happiness is contagious. The more you spread it, the likelier it is to come back to you. So why not? Go out there and appreciate all the things that are around you.
