Being idealistic isn’t the same as being naive. Don’t be afraid to hope for the best and wish for a more peaceful world. When you focus on making things better, you influence other people to do the same. It’s never a waste of time to talk about what’s wrong and how to fix it. Yes, there are certain things you can’t change. But there is so much you can change! For starters, you can turn a blue friend happy again just by giving them a call. Start with that.
