All the little things you do create the image or aura you have. If you’re not 100% confident you will do little things that give this away. There are two ways to fight this: 1) become 100% confident 2) be aware of and control the little things. Now the best path is the middle path in this case: take the hard road of becoming the most confident version of yourself but also work on the little things while you’re at it. So that in the mean time you will at least look confident, and when you eventually get confident for real it will only get better. Plus presenting yourself with confidence will improve your confidence as well.

By those little things I mean among some other things:

The way you walk. Your resting face Your face while taking. Whether you are groomed or not, and how. Your clothes. Your voice. The way you sit and stand. Your eyes, eye contact especially.
The way you hold things. The way you use objects. Your hands and body language. The way you smile. How you talk to others. How you behave when not taking to others. How you start and end conversations. The things you say, and how you say them. Your neck.

You’re outward persona, the thing people know you as, is made up of a lot of little distinct expressions. The only way to change your outward image is to handle those little things one by one at first.

Be aware of how you express these things now and if needed, improve them. There are enough online resources for this.

This post isn’t revolutionary in any way. The reason I made this post is because most of us forget about this. We are not aware of how we express ourselves and just assume that people are blind to us, or that they can smell our personality without having to observe how we express ourselves outwardly. We need to be aware that everything we do has an impact on our image, even the things we are not aware of. And that people can only understand us through our actions and outward expressions, so we need to be in control of these things so that people see us in the way we want to be seen as.

Basically: fake it till you make it. And what needs to be faked are the details of how you express yourself outwardly.
