Show passion! but not always and not at the same intensity

Intelectual passion is felt like some sort of energy. At high intensity you feel out of your body and afterwards you don't know what got into you. In the end you feel somehow changed. It is an amazing experience but quite all the time very intense. Anyway, intense feelings are strange experiences because they are not daily routines, you live it internally and it is indescriptive in words (others have to live in order to understand it).

After a interview en employee asked me why don't I show passion because she shows so much passion, when she talkes about her job . Then, when I was at a conference with foreign students (each of different nationality) they were amazed that I use so much passion when I talk. (in both cases it was about marketing and its practices). Something is wrong here.

Firstly, is it possible that we are assesed and classified on the passion scale by persons around us who are using their own level of passion? The assumption feels right, don't it?

Passion like all other personal attributes are judged by internal mechanisms which use comparison between us and them. Your level of passion is in the eye of the beholder.  

But we should always keep in mind that people are introverts and extroverts, maybe they are from different nationalities with diferent cultures etc.

Secondly,  passion can bring together people or can set them apart . For example if you meet somebody new, who is passionate in the same field and you start talking, both will say that you just clicked, will be amazed that there is another person that gets you and you will feel rewarded after that conversation.   

Others may be emberrased when talking to more passionate persons, from different reasons and reject that person because of fear of unknown. Usually persons that never experienced passion will be always expeditive with passionate persons. Just because they don't know the feeling, looking from outside, they find it odd and messy, they will laugh or change the subject.

Anyway for the both persons the conversation will be a failure.

From these assumptions derives a series of questions:

• when is it ok to be passionate
• how to find if your interlocutor knows what passion is 
• how to determine the right level of passion 
• how to speak the same language in social contexts (eg interviews, parties etc)
• how to gain advantage from your passion?
