The time taken to create an impression varies from time to time, person to person, situation to situation etc. It depends on the outlook that is fashioned on the other individual concerning you based on your outward show, your body language, your appearance, your mannerisms, and the way you are dressed. Remember, you are being evaluated in a first meeting. In normal cases, first impression cannot be reversed or altered, so building that first impression is exceptionally vital, as a tone that will be created in first meeting will be continued with further relations with the person. Hence, whether they are in your profession or societal life, it's imperative to know how to build up a good first impression.
Smile
A smile is a declaration that, “I’m open as well as harmonious.” It is a path that leads to a sound relationship.
Be Comfortable
Being uncomfortable may make the other person irritated, it definitely stamps a wrong impression. If you are composed and self-assured, the other person will feel more relaxed, and so can establish yourselves and hence, the quality of the meeting will be on higher side.
Present yourself suitably
As all of us know, physical appearance plays a vital role. You are unknown to the person you meet for the first time. The way you present yourselves is generally the primary indication for the other person to decide on you. That does not mean that you go as a super model. Present yourselves in a way to suit the mood of the meeting.
Be civil and Attentive
It goes without saying that good manners and polite, attentive and courteous behavior help make a good first impression. In fact, anything less can damage the one opportunity you have at creation of that first impression. So be on your best performance! One present manner appeal mention is switch off your cell phone. What kind of impression you will generate if you are already speaking to somebody else than the person you are meeting for the first time? Your new associate deserves 100 percent of your interest. Something fewer and you'll form a less than good first impression. Raise your eyebrows. Open your eyes a little more than usual to create the “eyebrow blaze” on his/ her comments; it is a sign of appreciation and acknowledgement.
