Be kind and considerate and most of all, just be yourself. I think remembering names help, hehe, since it shows that you're interested in a person, also, I think being helpful helps too, I've known a few seniors who watch their juniors walked for distance with tons of stuffs in their hands and never offered to help and that's not very nice. This is not really a must but I think that people find it easier to get closer to someone who is easy going and not overly reserve and quiet. Well, that's just my point of view. =)

Just be yourself and if other people don't like it then its just tough, you shouldn't need to put on an act to make people like you, if people don't like you for who you are then they are not true friends.

Just realise that not everyone will like you. I tried for 15 years to get some of my husbands family like me, sometimes acting like a total doormat in the vain hope that they would like me. You have to realise that you are a nice person and that if they don't like you, then that's their loss, not yours. Sometimes, I think that if you try too hard, that will put people off as well.

For others to like you, you must first like yourself. Don't take yourself or anyone else too seriously, be nice and smile a lot. Things you shouldn't do are: be mean, bitch about others or go off your head at something that hardly matters. Just be yourself and you will attract the right people =]
