Real or Fake?

How important is it to people to be liked? I thought about this a lot the other day. I like to be liked, it actually means a lot to me. But do people want to be liked so bad that they change how they talk and act to make people like them, or are they true to themselves, and let the real them show? I mean do you really want to be friends with people who don't know the real you and only know the fake you? Is it really worth it to forget about who you are and just act how you think they want you to act. I've made some great friends here and I feel like I was the "real" me and they all accepted me for who I really am. But I know that in the past I've done the "fake" me and acted how they wanted me to in a group. I've realized I'm a much happier person now that I have friends and I can act like me and be accepted in the group. But it makes me think about whether my friends feel like they can act like themselves in front of me. It is important to me for people to like me. I do things to impress people, and usually go above and beyond to be nice and make things easier on people and less stressful. But there's a point when being liked isn't as important as being able to be the real you. Where do you draw the line?
