It feels virtuous to care about the news because it goes beyond the self. Stories–never happy–almost exclusively cover some kind of tragedy and evoke your tendency towards compassion. How could you not care about catastrophes?
Have compassion, but recognize that your inability to solve such problems makes caring about them unproductive. Instead, solve your own problems. Then work on those in your family. Then those with friends. Then those in your community. Make an impact on the world by changing yourself and those around you, operating only where you can control. Impact your world by ignoring the world.
