How to do that????

How do I change from who I am to who I want to be??
I don't want to talk at all to anyone...everyone is acting out there (in fact I met very few people who are really living)
but
I have this humour, I make others laugh, the glow in the faces of people when they laugh...OMG anything is worth it.

I want to be a full length Introvert.
but
I keep circulating between an introvert and extrovert.

I want to do this social service (there is a reason for that).
but
I fear I would loose myself in it.

I want to shout at people who never believe that I have no reason for turning into vegetarian (I really don't have...i felt like that, that's it!!!)
but
They are my parents, relatives, close friends.

I love to live life to the fullest like MR. Lord Krishna who enjoyed life to the fullest and fulfilled his destiny too. I always wanted to be like him. Yes it includes 8 marriages too :P
but
I never loved a girl, never and i sincerely doubt it ever happens. Is there anything like so called love?? Hahaaa......my father keeps asking me "will you marry at least??". I in fact love to be single my entire life :P Atleast i can eliminate the need to act to impress someone. Atleast there would never be a need to compromise. I am who I am.

And


When I try to be someone who i am not. When I act, my body immediately warns me.
It doesn't even allow me to sleep; punishes me with sleepless nights. That's why I love my physical body...muahhhh!!!
