Balance must be created when taking in news media, not allowing ourselves to BECOME the bad news.
We are aware enough to know when we are eating something that is not good for us, because we don't feel well after we've eaten it. In the same way, we can determine for ourselves whether the sources in which our information comes are ultimately healthful. News can be presented in a way that inspires us to take positive action to help the world, or it can be presented in a way that leaves us feeling powerless and sad. It is up to us to seek out and support media that empowers and informs us, and to say no to media that drains our energy and our hope.
For a time, it may even be of benefit to commit to a media fast, in which we stop taking information in for a time to give ourselves a rest. When we return to the task of taking in and processing the information all around us, we will come to it with a fresh mind. This will enable us to really notice how we are affected by what we hear and see, and to make conscious choices about the sources of information that we allow into our lives.
