Sometimes I'll watch a movie and pick up a line I really liked. Last night I was watching movie, and a woman said, "people are stars, until you get to know them, and realize they are human". Most people that have crushes on people, usually don't know their crush that well, or they would realize they are just as human as they are. Usually it's the mysterious person that is liked more by many, because nobody really knows them. Once people knew them, they would realize their faults, and wonder and say, wow, they are just like me. Not any better. There is no good advice I can give on this, but that everyone looks prettier from a distance. You have really get to know a person, and make sure they are right match for you before you start dating them. Otherwise you will not be as happy as you could have been. Can't say wow, I went out with this one person one night, and we really hit it off, and now I'm in love. That just can't happen. Everyone is different, but humans think alike. Everyone is in good mood somethings, and everyone has their times when they are not feeling so good. Usually when person doesn't feel so good, it's because they don't feel loved. When person feels loved they instantly cheer up and are really happy. So be happy and loving and be really funny and everyone will like you, and return the love.
Sometimes you can be out in public talk to a nice girl, and have good conversation and ask her out to lunch, and if she says no, then it will be ok, because you don't plan to run into her everyday, if she turns you down. She also won't feel bad by saying no, if she is not interested, because chances of you two running into eachother again are rare. On the flip side, maybe you like someone in a class, but you don't want ask her to do something, because you are worried she might say no, then later, she might decide she likes you, but your feelings were hurt, and you aren't interested anymore. Same type of thing at work. So if you are interested in someone that you will see everyday, ask them to do something stupid. Like hey, I need go to run an errand and buy socks, do you want to go with me. Then if she says no, I don't want buy socks with you, maybe she won't want to go because she has other things to do, then buy socks with you. But if she really is interested in you, then she'll say, ummm, well, I guess. Things won't feel uncomfortable, and you will get know her better without feeling ackward.
As you grow up, your life changes, your environment changes. You may feel somewhat lost. Nobody is telling you where you have to be or what you have to do. You may feel more free then ever, but more lost at the same time. It's obviously more difficult to make friends when you are not with a group of people you enjoy their company and are all working on the same thing. You may picture that your life would turn out much differently and you would have so many friends when you grew close to your 30s. After having so many friends in college or high school, you may feel like now you don't have many friends. It is comparable to having a lot of money, and then seeing that you don't make as much money as you used to make. It is natural as you grow older to have fewer friends if you are comparing your life to previously. Friends are very important to being happy, you can't just be happy with yourself. If you find yourself wondering why you don't have so many friends, then maybe you should start talking to people. Everyone has time for at least one more friend. Everyone goes from having many friends to less friends. It's very common. If you make no effort to become friends with anyone, then they will just think that you have enough friends, and don't need anyone to make yourself happy. If you are a friendly person and talk to everyone, then chances are you will make a lot of friends.
