THINK ABOUT YOURSELF

-
  What is the purpose of what you are doing?  What do you really want to do?And to what end?It's like the dreaded interview question.Where do you see yourself five years from now?where do you see yourself at the end of this journey you have embarked on so that, i would say, became my purpose to shape ideas, to make sense of the news,to empower you, to form your on opinion.You have a story, but why should anyone listen to it?There are multiple channels with heavyweight anchors all discussing the same story with same guest, the same graphics, the same visuals,and the same decibel levels,we all kept looking at each other and perhaps forgot the viewer.We wanted to do what someone else was doing.Bigger, bolder, brighter, but not necessarily better.We do not plan
