How to have better conversation

Most of the time during conversation we pick some topics which are not convenient like politics, or religion because everyone has a different beliefs, and that would cause conflict, so always pick topics which can be simple, or easy to discuss, and don't let other things take away your consciousness from certain topics means when you are already in a conversation then don't think about other stuff in your mind, and sometimes we make assumption about others through our beliefs without listening properly what they are saying, so best way to fix that problem is to learn something new from them because everyone has unique knowledge about something that we don't know, and try to see things from their prospective because their definition about life might be different from yours, and don't take things personally, and be light, and positive then there will be no argument during conversation, so respect others opinion, and they will do same for you because everyone has both good, and dark side within in, so it's totally depends on you which part you want to evoke. At the end of the day make your speech as brief as possible because long speech would make you feel tedious.
