People tend to bond more effectively over topics that are positive instead of negative, critical, or harping topics.
To initially make and to start to talk a topic about which both/others are passionate instead of resorting to insults or criticisms in order to generate a great and healthy conversation is one of the best way to move forward in a conversation.
To think about it let us make scenario and relate a topic to it like
If you are in a dinner party how will the outcome be making negative comments will make the environment formidable than ever .
The suggestion would be :
Don't make small-talk at a dinner party about how much you hated the soup: talk about how you enjoyed the dessert instead.
It is also a good idea to resist debating with your conversation partner. Share ideas respectfully without resorting to negativity.
Be positive and make positive decisions.
Keep going everyone has flaws give time and try to overcome them.
