Short: Presence is an ephemeral term that can mean a lot of different things to different people. What I'm talking about in this post is "the glow". "The glow" is when someone enters a room and you immediately know there is something special about that person. Bill Clinton has this effect. He doesn't need to speak a word for you to know he is someone special. Presence is something you can learn and create. A large part of acting is creating presence. This post is some meta based on my own experience for creating "the glow" in every day life.
Long: Ultimately presence and "the glow" in my opinion is just the set of body language that hints at power. People pay attention to powerful people because they don't want responsibility. So ultimately presence is when someone is used to leading and it shows. I think presence manifests itself in different ways depending on the type of leader a man is.
Women like people with presence because women are attracted to power.
The list below is some actionable ways to improve your presence. They are basically ways to stretch your leadership muscles. As your leadership confidence grows, you will naturally gain presence.
1 - Own your flaws and mistakes
Explanation: This is number one because it is very easy and is a strong sign of a leader. Everyone has flaws and makes mistakes. Leaders know this, and are especially aware of their own flaws and mistakes, but have forgiven themselves for them and have accepted that their blemishes are an important part of their ultimately triumphant story. This is basically "agree and amplify" except in your whole life.
Example: A very easy way to become the defacto leader of a group is when there is an issue, to take responsibility for the problem and fix it. For instance lets say your boss says at a meeting, "Look guys this is a big issue that we can't have happen again, I need to know what happened." An easy response is "Boss, I know what happened. This is my fault. I should have made sure it was checked more often, and I'm going to starting today." I like to think of this as "responsibility vacuuming". You're basically covering everyone else by assuming the blame. However, because no one blamed you there is no social stigma attached -- instead it is only positive socially because you are taking care of a problem everyone was worried about. In addition to getting social brownie points, you are now the leader of a process and have the responsibility to delegate to other people. This thought process is only possible when you are comfortable being the one at fault. So own as many mistakes as you can, except if they are being directed at you as attacks (and even then it is sometimes a good decision to own them).
2 - Create a strong internal identity
Explanation: The strength of your internal compass is a good indication of your presence. When you feel entitled to things that most people don't, it is visible as presence.
Example: The exercise I recommend for disassociating your identity from the way people react to you is dressing differently. Think of a crowd of people you feel uncomfortable around. For example, when I was growing up I wasn't comfortable around rednecks. Do a google image search for that group and go buy clothes that mimic what you see. For instance, for me it would be a camo T-shirt, john deere hat, and dickies jeans. Now wear this outfit around for a day and experience how differently people perceive you. The point of this exercise isn't to be someone you're not, it is to open yourself up to the idea that the real you is hidden from the world. The facade you call yourself isn't the real you. The way people react to you isn't based on who you are either, people react to you based on what they see. People can't always see the real you, so you should never be concerned if people think poorly of you in any situation. They can't know.
3 - Speak at full volume and at your own pace
Explanation: This is one you've probably seen before but I want to explain it differently than I've seen it explained. Leaders speak slowly because they don't care if someone will talk over them. People don't speak over leaders because they don't want to be socially stigmatized. So think about your speech and speak it at your own pace. Don't worry if someone speaks over you. You can always speak over them or unfortunately let them make an ass of themself. As far as volume, the right volume is as loud as you get without using extra breath.
Example: I am literally linguistically retarded in some kind of Aspergersy way -- I couldn't read well until the 4th or 5th grade. So for me this goes back to the first example in owning my flaws. When I'm speaking to someone my mental thought process is "I am kind of retarded in speaking, so this is just the way I speak". When I'm speaking I spend all the time I need thinking about what to say and say it at a speed I won't stutter or stumble at. While this is just my personal limitation, people also know I just DGAF what they think. The person I'm speaking to typically becomes submissive and does what I want, even fairly alpha dudes. One exercise that may help you if you have trouble with volume is to sing as loud as you can as often as you can (in the car, in the shower, etc). I've found cranking the volume in my car to max and singing as loud as I can naturally raised my vocal volume over time.
4 - Visualize your personal space
Explanation: Have you ever been at a movie theater and felt uncomfortable bumping elbows with the person next to you? If you are the one who "retreats" and puts your elbows off the arm rest, you probably have a small personal space. People who have presence have very large personal spaces. However, the point shouldn't be to "win the armrest" -- someone with presence definitely won't battle over the armrest. The reason is they simply don't care if you're touching elbows because you are part of their personal space -- in other words in their mind they own you (as though you were a part of their body), so to them touching elbows doesn't feel awkward, its actually quite pleasant.
Example: Visualize your personal space as a bubble right now. If you are in a room you own you will probably have a fairly large bubble. The next time you go out into the public visualize your bubble. If you are socially awkward, your bubble will be right up against your body. Make an effort to visualize your bubble as being bigger and bigger. Make an effort to relax in your personal space that you carry with you. Its your place and you get to make the rules there. Eventually, you can extend your bubble to the entire room or maybe the whole world. Eventually you may start viewing people in your personal bubble as "your" people. These people in your space are your people so you don't need to worry about them. In fact you want them to thrive because they are as much a part of you as your left big toe. When you get this perspective you will be okay touching strangers and your main concern when speaking to a new person will be making them feel good. This is what it feels like to have very high level presence like Bill Clinton.
5 - Do what you want
Explanation: This is a cornerstone of TRP. Being confident is a big part of attracting women and this gets reiterated over and over. People with presence are confident, so they also do this.
Example: One way to stretch your "do what you want" muscle is to go to a bar and watch the TV and talk to no one. At a bar its uncommon for someone to do nothing, so you will probably get attention for not being social. Figure out the rest yourself based on what you want. Don't be surprised if a woman or three accidentally bumps into you.
Takeaways: Presence is a mindset you can learn that people notice and respect. Remember: 1) Own your flaws and mistakes 2) Create a strong internal identity 3) Speak at full volume and at your own pace 4) Visualize your personal space 5) Do what you want.
