agree or disagree?

It is unlikely that you will meet someone with whom you agree about everything, or with whom you will disagree about everything. What is your first impulse when you meet someone for the first time? Do you look for areas in which you disagree that you may set them straight or avoid the influence of their errors? Yet unless your knowledge is already perfect then they may know something you could benefit by learning. If you start by looking for areas of agreement then you will have this opportunity that you would miss if you started looking for disagreement. Cast your net wide and then sort out your catch.
