You can spend as much time as you want to choose the most beautiful picture and then put it on Instagram's Facebook profile, but in the end the choice is known. You will choose the one that expresses more details of your personality; with or without consciousness.
This election also conveys what others see in you! What do they think when they see your profile picture?
If you put your smiley face profile as your profile picture: You know what people expect from you and how to behave in certain situations.
If in profile photos you come up with other people: You are likely to be a very extrovert and sociable person. These types of profile photos are often indicators of a young age.
If your face does not look: If you choose a pose where your face is hidden or does not look good, it shows you are open to new, non-traditional and non-conforming things. Rely on your principles.
If your profile picture is messy: Many elements, colors, objects in the same picture that create the impression of a mess, speak for a relaxed man who does not deal with trivia. Likewise, for those pictures where the background is not 'perfect' but there are scratches, ruined walls or any other details that other people would not save.
If your photo has so much light, you can hardly look like a face: You are a person who wants to be liked, and suits others, more than yourself.
If your picture is dark, and your face is very close to the camera: You are a man prone to fasting and jealousy, and you quickly get stress and pressure prey.
