How to Get a Girl to Like You

Every girl is different, and there are as many different ways to attract a girl as there are girls. That being said, there are some basic principles of attraction you can apply to most situations. To get a girl to like you, you'll need to get noticed by being her friend while simultaneously flirting and testing the waters of romance to avoid the friend zone. When the time is right and you think your feelings might be mutual, you can ask her out to seal the deal.

PART 1
Get Noticed

Have your own life.
If you tend to fall into the "friend zone," this will be especially important. Real girls (girls with a strong sense of purpose and self-worth) don't like guys who have no lives or who cling to them like plastic wrap. Some girls do like that, but for all the wrong reasons—either they're insecure and needy for attention, or they're control freaks who have a need for dominating guys. Unless you want to sign up for one of those scenarios, focus filling your time with your own friendships, interests, hobbies, and goals. This also gives her a chance to do something with you without it becoming a date.

Look neat.
Keep yourself well groomed and in shape. If you want to get a girl to like you, basic cleanliness and appearance are extremely important. Girls notice things like bad breath, flab, body odor and greasy hair before they notice that winning personality. Give them a chance to see your good qualities by making a good first impression with your appearance.
Stay in shape. Work out regularly: run a mile or two, do some sit ups, get a six pack, etc. Note that while fitness is important, you shouldn't overdo it; having too many muscles can make it look like you care more about going to the gym than fostering meaningful relationships. Also, some girls dislike having the Incredible Hulk as a boyfriend, and it makes you look slightly stupid - thanks to the dumb jock cut-out. So make it clear you're fit, but not thick. In other words, stay fit without being obsessive or a pair of walking biceps.
Have good personal hygiene. Brush your teeth, shave etc. If you can't have access to a toothbrush, carry breath mints. When you take care of yourself, it makes you more appealing to others and it will thus have a positive impact on your level of confidence. Always be sure to smell and look nice, so shower regularly and nothing is worse than the post-gym stink out, so use deodorant.

Speak to her.
It's unlikely a girl will be at all interested in you if she doesn't know you exist. Make an effort to talk to her, even if approaching her seems scary at first. Highlight your compatibility as friends and more by talking about hobbies and interests that you have in common. Become her friend; she can't get close to you unless you're friends.
Find a hobby you both like. It doesn't matter if it is anything from sports to school. If you both like hockey, invite her to a game. If you both like video games, play one together, or she could cheer you on if she doesn't usually play. Girls are all different in likes and dislikes.

Make her laugh.
Telling jokes or funny stories is a classic way to make a person laugh, but not the only way. Be bold and think of some antics that will make her laugh, like clowning around. Find out which are her favourite comedians, funny movies, or sitcoms. Watch them with her. Tell her to dare you to do something, then do it (as long as it's not illegal, of course). Laughter will come by itself if both of you are relaxed and enjoying each other's company. The more she laughs, the more she wants - and she will want more.

Be her friend.
Girls don't just fall for random strangers. (Well, some do, but the relationship never goes very far!) Start being friendly to her in a non-invasive way. Get to know her and begin hanging out as friends.
If you're in the same lecture or tutorial as her, find out her name. Every time she walks into the room, smile and wave at her. Sometimes this is all it takes for a young woman to notice you. At the same time though, don't do this too often; It will just end up looking like you're obsessed with her. If you're worried, greet some of your girl friends as they enter, too. If she doesn't seem to see you, when she walks by, just say "Hi _______," in a friendly way, but don't interrupt the class or any conversation she's holding.
If she's shy, she might just smile back, so don't take this as a sign that she doesn't like you.
If you want your relationship to move ahead faster, don't get stuck in the quicksand - that is, the 'Friend Zone'.
Sometimes, a girl won't go out with you because she's afraid if the relationship will end badly, but that she'll lose your friendship! To start moving things along, be a little flirty; a woman will only be intimate with a man she knows, trusts and cares about, and this can only be achieved with taking the time to get to know her through friendly chat. However, don't come on too quickly - part of the fun of the relationship is the chase - and have patience. Girls HATE being forced into something, especially on the relationship front.
