It is rightly said,"What comes out of your mouth is determined by what goes into your mind". Our society is more negative than positive. Our conversations at home accentuate the negative. Unfortunately, a negative thinker activates the world around him negatively, and every bit of negativism he sows produces a bumper crop. Albert Einstein said we have to have seven positive influences to overcome one negative one.
Change emphasis - change results. Take one day and after each encounter jot down the gist of the conversation. I promise you, by the end of the day your comments will be more positive than they were at the beginning. Once we become aware of what we are doing, the solution is on its way.
