In an ideal world, you would get along with every single person in your life with no problems or issues arising at all. We all know, however, that that simply isn’t possible! The thing is, having disagreements and arguments is totally natural, the important thing to grasp in these circumstances is that you should always be trying to get something out of your argument, make some sort of progress and just not leave things in a big shouting, feelings hurting mess. Here is how to have a constructive argument that doesn’t feel like it has been totally pointless.
You are never going to be able to have a constructive argument if you don’t listen to what the other person has to say. If you are going into conflict just to shout your own piece, then that isn’t an argument, it’s just a tirade. Make sure that you have an ear open to the words of the other person, and that will be able to much more effectively guide the discussion to something resembling a compromise or conclusion.
