Turn off your phone (or at least mute it), turn off email and instant message alerts on your computer, don’t doodle, and most importantly, focus on the person or people you are speaking with. It's hard to get to know someone when you're looking down at a screen, so make an effort to make some eye contact with everyone in the room.
However, keep in mind that eye contact can also backfire, according to a study by the University of British Columbia. If people aren’t already persuaded or inclined to be on your side, they may focus more on your mouth or any presentation materials you’re showcasing instead of your eyes, making attempts at eye contact a challenge.
