• Do not under any circumstances, tell him you like him if you think he doesnt like you. If you do you could seem pushy and he will definetely say no. sometimes acting differant arround him than others is a good thing.
• You can't get everyone to notice you. Remember that guys come and go, so do not stress yourself if things do not work out in your favor. The world is a really big place, and you'd do well to remember it.
• Being too obsessive can do the opposite of what you want to achieve, pushing him farther away. Under the category "Love", obsession or suspicion doesn't fall in. That is "Infatuation".
• If he just won't become attracted to you, leave it alone. Do not push it, or things might get ugly, and you'll earn a bad reputation.
• Don't show off too much flesh, especially if he would always look. Always keep him under suspense. Also modesty shows that you are a lady. He will see that you don't need to show off, and in return the right kind of guy will give you his respect.
• Do you like cocky people? Self-centered people? Bossy people? In-your-face people? If not, then avoid being any of those, because he probably feels the same way. Don't boast about yourself constantly [he'll think you're nuts], don't think only for your benefit, don't push him around too often [especially when you're doing something in a team], and don't always ask questions about him or you.
• If he doesn't seem to be getting all the hints after a week or two that's okay. It doesn't mean he doesn't like you; it just means he may not be ready for a girlfriend right now or that he is too shy to show emotion back. If after maybe 3 months of being flirty then he probably isn't into you as much, it could still change. It's completely up to you how far you'll go, how hard you'll try, how long you want to keep it up, etc.
• Don't act like a snob to impress him. He will think you are obnoxious. Also, don't be clingy or bother him. He will try to avoid you or think you are annoying, and you don't want that.
• You always have to be yourself no matter what. If you act like someone else you could end up with a guy you don't like.
• Don't force him to like you. If he doesn't, don't feel too bad, he's the one who's missing out. Let him meet you halfway at least. Like everything else, things can change over night. Sometimes you need to give him some space to think about the idea of you & him. It'll take you a while to figure out how you'll try to get his attention in a positive way, so give him some time to find a reaction that he sees fit.
• If he is in the popular clique, don't try to join in the group. If you do, they'll probably talk about you behind your back. This could start rumors, and he may not defend you. You know how cliques are, right? They prefer keeping people inside who stand by their beliefs.
• Wish you the best of luck, and remember that whatever happens, no one can change who you really are.
• If you are under pressure, just relax, kick back and maybe rehearse a few lines, but feel free to make up something, as long as it sounds nice. Don't do the perfume on the arm and ask him to smell your arm.
• For some reason, girls think guys notice him if you're loud. Don't shriek so loud you hurt the eardrums of the person next to you. It's not going to do anything, anyway. Just walk up to him and talk to him, but you don't need to be loud.
• Make sure you listen to him and not just keep babbling about yourself maybe you could learn a little more about the guy you like than just his hair color, eye color etc.
• Clinging is not right. You don't need to sit with him every day and take up an instrument because he does. Sure, he might be impressed, but ultimately it's your life. You need to learn how to balance your time. Don't sacrifice just to get a guy.
