Should I change or Should I not !!!!

Everybody has his/her weakness, and I am no exception to it. And talking about them I have a long list. I am arrogant, I am talkative, I am egoist, I am way too informal, and I don't usually give a damn about those whom I dislike.

But then the good thing is that I know about all these negative traits of mine, so after listening to a lot many suggestions from people about whom I do care, I thought why don't I try to change myself. To change myself into a normal being who listens to and agrees to a lot many things he/she knows are incorrect, who doesn't laugh at some-one even if he/she is saying or doing something utter crap. Now one cann't change oneself in a night so from past 3-4 years I was trying to have these traits in myself. As of now I have been able to change myself so much so that if some-body is giving some crappish gyan I just manage to have a smile without uttering a word(as far as I can resist).

But then some-how I began realizing that no matter how hard you are trying to improve yourself, you will always have people criticizing you for one thing or the other, and if you are restricting yourself from making comments on others then you will find a lot many people passing them on you, and of-course the Public is there to laugh at every such opportunity without even trying to figure out who was the dumber one.

And more-ever no matter how much you have improved, or how much CIVILIZED you have became, they will always come out with dialogues like "you anyways never accept anybody else's view" or "don't talk with him, he never agrees" or something else like that, and when you are actually taking pain of changing your-self just because you don't want your closed ones to feel hurt.(Though I understand that it must be happening quite a few times and I sincerely apolize for the same). So its then that you actually feel hurt, you feel like killing youself coz you are trying to be like NORMAL guys and you are constraining yourself from saying something that may hurt them.

Now, the dillema that I face now is that whether the effort that I am trying to put in changing myself from being myself to a NORMAL guy is actually worth the juice.
And I don't think that it actually is.
I am already feeling that I have lost the touch of magnificient spontaneity and God like confidence which allowed me to be care-free even one hour prior to the board exam, playing cricket and dreaming, which allowed me to be a hope of the school in case of any improptu occasion where a speech had to be given or a thought to be read.
Plus atleast I didn't feel bad when some-one came out with the same dialogues I described earlier coz I knew that this was the way I wanted to be.

With the negatives of this change discussed lets come to the positive ones.
You feel good that you are changing, yes the feeling of doing something is actually good. People who knew you from long time get surprised when they see the new you and this feeling is as good as the earlier one. And the last and the most important one though probablity of hurting your beloved ones is there in both conditions its much less if you are NORMAL.

And though I don't care much about it, but yeah a lot many people start coming in contact with you, thus giving an illusion of a larger and hence better (not for me) friend circle.

Now plzzz if anyone of you can suggest which way should I go, I will be really glad.
