When you want someone else to be aware of the confidence you have in yourself, you should keep your hands away from your pockets. This, by the way, also works well to make other people trust you. Putting your hands in your pockets shows nervousness, insecurity, and a need to hide something or keep your distance. That’s why it’s better to simply keep them in sight and in a relaxed position.

Consciously or unconsciously, when someone feels confident, the separation between the fingers of your hands is usually greater, you tend to raise your thumbs a bit more, and bring your fingertips closer together.
