The dictionarys definition of presence:
The ability to project a sense of ease, poise, or self-assurance esp. the quality or manner of a persons bearing before an audience.
My two cents:
Professional presence is about exuding energy. It doesnt have to be hyped up. It can be quiet and calm energy. As long as its positive, project it.
Appearance is important. We make judgments based on the visual data we gather. Dress and grooming are important clues we project each time we encounter someone.
Smile. Make it a policy.
Good posture can give you energy and power and convey confidence.
When you enter a room, attend a meeting, or conduct business, show up ready and fully present.
Attitude isnt everything but its practically everything.
To create a winning attitude, you need to (a) smile as much as you can; (b) say hello to people even if you dont know them; (c) initiate a handshake and (d) always have something positive to say.
Seventy percent of communication is non-verbal. If you look successful, youll be perceived as successful. Perception will always trump reality.
Work clothes are not play clothes and vice versa. Professionals dont blur the line between the two.
Effective virtual communication (whether by phone or email) starts with a friendly and upbeat state of mind.
Dont forget to say thank you.
