6. Do not interrupt the person
Whenever the person you are with is talking or making a point, you should not make mistakes like interrupting them constantly. You must allow them to complete their talk. Interrupting frustrates a person and makes a sustainable conversation impossible.
7. Maintain eye contact
You must maintain a decent eye contact while introducing yourself. However, it should not be something fierce which may scare the person. All the way through the conversation, it is necessary to maintain an eye contact every now and then.
8. Do not judge
The person you are going to may have a set of views different than that of yours. You must not be judgemental.
