Despite words, the body has its own language that makes you add more appeal in your personality. Those like to sit with hands on the table and face covered with hands show the sign of utter disrespect. The ideal thing to do is sit straight in a self-confident position that is sure to attract the attention of others.

Showing some expression more than it is required, simply means one is lying or does not want to show his/her true feelings. This sort of body language is certainly not good while making a good relation with the people.

Sitting or standing with cross-hand is another body language which is considered wrong. It simply means, one is not at all comfortable with the situation. Doing this will surely make you feel inferior in the eyes of others.

Doing a handshake is a true sign of professionalism that should be done with care. Handshake with weak grip is a sign of lack of confidence in you. The ideal way is to give a bone-crushing handshake in order to showcase your self-confidence and integrity.

Playing too much with hair in between the conversation or discussion simply means, you are not paying attention to it. This sort of habit simply shows your insecurity towards the others.
