Most people will judge you within the first second of meeting you and their opinion will most likely never change. Making a good first impression is incredibly important, because you only get one shot at it.

Princeton University psychologist Alex Todorov and co-author Janine Willis, a student researcher who graduated from Princeton in 2005 had people look at a microsecond of video of a political candidate. Amazingly, research subjects could predict with 70-percent accuracy who would win the election just from that microsecond of tape. This tells us that people can make incredibly accurate snap judgments in a tenth of a second.

How can you ensure people are judging you accurately and also seeing your best side? You never want to give people an inauthentic impression — many people can intuitively feel if someone is being fake immediately. However, any time you meet someone for the first time, you always want to start on the right foot. Here are a few ways you can make sure people’s first impression of you is a good one:

1. Set an intention. The most important thing to do for giving a good impression is to set your intention. This is especially important before any kind of big event where you would be meeting a lot of people — i.e. conferences, networking events or friend’s parties. As you get ready or when you are driving over think about what kind of people you want to meet and what kind of interactions you want to have. This can be an incredibly grounding experience and works very well to focus on what kind of energy you want to have for your event.

2. Think about your ornaments. Clothes, make-up, jewelry, watches and shoes are all types of ornamentation and people definitely take these into account when making initial judgments. I highly recommend getting some of your favorite outfits or ornaments together and asking friends you trust what they think of when they see them. For many men, they do not realize that their watch can say a lot about them. For women, purses and large earrings or jewelry can also indicate a lot to a new person they are meeting. Make sure that what you are wearing and how you do your hair or make-up says what you want it to say to the people you are meeting for the first time.

3. Be Conscious of Your Body Language. Body language is a crucial part of first impressions. Everything from your posture to how you carry yourself to the way you’re angling your body. Often, simply being aware of your body language can result in immediate improvements. Another way to examine your body language is to look at yourself on a video walking around a room. Subconscious cues to keep in mind include noticing where you point your feet, the position of your shoulders, and the way you shake hands.

4. Avoid bad days. People who go to cocktail events or mixers after having had a bad day typically continue to have a bad day. If you are in a depressed or anxious mood, others will pick up on this from your facial expressions, comments and body language. If you’re having a bad day, stay home! Otherwise, find a way to snap yourself out of your bad mood. I find working out or watching funny YouTube videos before events often gets me in a more social, feel good mood.

5. Be interested and interesting. If you are truly interested in meeting people and are open to learning about who they are, they will get this in a first impression. We have all had the experience of meeting someone and knowing instantly that they were dragged here by a friend and are just waiting to get out the door and head home. When you are meeting people for the first time approach others with a genuine interest in who they are. This is often contagious and you will have better conversations and lasting connections when you are interested because they become interested.
