Who thinks there is too much negativity in the world? (Can I see a show of hands)? Yes, I know how difficult it can be to stay positive when you are surrounded by negative energy, but there are things you can do.
The latest argument between Joy and Meghan getting you down? Turn off The View! Good honest discussion is always a good thing, but constant bickering is another matter.
Do you have a Debbie Downer at work or school or on social media? Show that person the high road and the benefits of being positive. If it doesn't work, don't let them drag you down. Move away from them and toward those brighter lights.
Don't sweat the small stuff. A very wise person once said this to me and it is so true. Some things seem very important at the moment, but step back and have proper perspective. Maybe your current situation isn't that important after all.
Stay healthy. Positive people are generally healthy people, or those who are trying to be healthy. Yes, colds and illness may show up, and sadly major medical conditions may arise. Work through the situation though and attempt to have a healthy body. Diet and exercise play a big role here.
Don't worry if you are not always happy too. It's okay to be sad about certain things. We all might have those bad moments. You can still be positive though even in the face of sadness or sorrow. Set some goals too. Knowing what you are looking for in the future is a very positive attitude.
