I want to eliminate negativity in my life. Unfortunately, that is not possible and might not be possible for you. Therefore, you have to learn to ignore negativity you cannot eliminate.
What I am talking about here is negativity from family or coworkers. You might find that you cannot cut these people out of your life. You have to keep seeing them, and when you do, they will spread their negativity around you. Ignore negativity coming from these people.
