Am I a poser?

If you feel like you are faking it, you might be. It really depends whether the image that you are putting out there is one that feels good to you, or one that makes you feel awful. If the self-image you are projecting is one that feels good to you but you think is fake, keep going. It may be your own self-doubt that is stopping you from believing you are that cool. If, however, you are projecting a self-image that doesn't feel good and you are doing it for the sake of the acceptance of others, you might be posing.

If you feel drawn away from the version of you that you are most comfortable with, you may feel you are a 'poser', what you should consider is your motivation - maybe you pose because you aren't ready to expose yourself e.g if you hear peers opposing your views. Or perhaps you are trying to keep people happy, e.g not using your intelligence as you don't want to correct someone in their moment of happiness and contemplation. Ultimately, you should feel comfortable in how you present yourself and with practise, understand when its ok to hold back or adjust for others, without feeling like you are selling yourself out just to conform or be likeable.
