Whether you are going on a job interview or meeting with a client, your first impression can literally make or break the deal. It usually takes an average of just seven seconds for a person to make a judgment about you based on your initial meeting. If yours is not a good impression, chances are you won't get the job or seal the deal. But if you make a great first impression you can bet that people are going to take you seriously, whether it's a potential client, boss or other business contact.
