Being Extrovert

How does being an extrovert helps? People generally dont like to be an introvert, not even ambivert.. I had always tried to be an extrovert and am practicing it. As result of being that, I developed a notion about myself "Whats on my mind implies What I say and do".. Today I feel like analyzing upon this..
I agree that this has given me much satisfaction at many times, coz u dont have something hidden in ur heart. Its better to speak out whatever u feel like. It helps u remain stable and open in ur thoughts.. The question I generally face is, Is it really helping me?? Many a times it works against me..
People can judge u more precisely, know whats on ur mind, have their own strategy for u, and u can do nothing coz u are already an open book.. They have very less to guess about u..
Its like, u wont buy a toy that has a minor crack.. But if that toy is packaged nicely and if u dont even now whether that toy even works or not,, even then u may opt to buy this.. The same principle apply to characters and human beings.. Thats why I wonder, is it helping me.. If someone reading, feels that he can help me with his opinion, u r welcome !!

One of my friend often reiterates on me certain things like, "Kyon Bataun", "Kya hoga Bolke", "Koi fark padta hai kya", etc.. And many a times I had been thinking this, "Does it really matters behaving an extrovert?"
Frankly speaking,, at the current instance,, I am really confused about these thoughts of mine. Currently I know one thing, I am taking some time to think about it and decide which way I wana head !!
