A old proverb signifies that a amount of fear in mind could smash decades old planning. So whether conversion or any social gathering, there should be no space for any confusion or any fear. You should know what you have to speak. There is no need to beat about the bush.
One important thing in conversation is the listening part. A man can only become a good speaker when he is a good listener. Listen properly and bang your reply energetically and furiously.
A conversation is the testing time of your attitude, personality and body language so one has to learn the art to control it. Confidence and practice are the bench marks which brings all these qualities in a speaker. Be confident and win the world
One must remember the importance of having the good communicating skill. All the great leaders, freedom figthers, visionaries, rulers- all wee the great speaker. Hitler could never rule the world had he not been an effective speaker and easily afraid from the crowd. Gandhi could not be able to lead crores of people in India if he had not convinced the people with his effective words. Effective words are even more stronger than a nuclear bomb.
2) One needs to be streight while talking to other person. One needs to be outspoken but some amount of diplomacy is definitely required. you need to learn how to control yourself when the things are moving away from your hand.
You should have one thing in your mind and that is I would do it first. I would bell the cat. I would take the initiative and win the whole world.
