An Open Book is an Open Book.

Your presence must make an impact, otherwise your absence won't make a difference.  How you leave others after an experience with you, becomes your trademark and therefore it is very important to take the opportunity when it comes, to make a suitable impression on those you connect with.  You may have a short time with them and the context in which you meet with them, may be business orientated, or on a social level. The circumstances become less important than the way in which you conduct yourself.  The old traditional things are still relevant, in my opinion, such as looking someone in the eyes, extending a firm handshake, having manners and remaining humble in the way you treat others.  Always treat those you meet for the first time, in the same manner in which you yourself would like to be treated.  These may seem archaic or even rather cliched, but they are still the foundation of contact with others and best not lost.  Unfortunately in my view some aspects of technology, have resulted in personal contact being less personal and human interaction is becoming far less personal and far more guarded - you need to cross various firewalls to penetrate a personality.  Nevertheless, our country still has people with personality and interaction with others is a very positive aspect of our society.  Time is another factor which is constantly being eroded and this to is an essential part of making an impression, when interacting with others.  Do you take the time to acknowledge others and grant them an opportunity to speak, or offer a different perspective to yours, or do you rather cut them down, giving them little or no time, to interact with you.  Have patience with those who are older, less educated and less skilled than you and make sure, that the questions you ask are of a genuine nature and not cryptic, or false.  Above all, be the person you normally are in front of others and the impression you make, will at least, if nothing else, be a genuine reflection of the person you are striving to be.
