How to Start a Relationship

Be awesome at anything; if you are smart, show it off, if you are funny, make her laugh, or if you are good at sports, give a demonstration. Let people know how you are different. Look far and wide. If you find yourself without 'any prospects', then you are probably not looking in the right places. Think of what you like to do that defines who you are. Ask yourself, where would someone meet me ? If you're into sports or exercise, then look into places where people do those activities.
Look for someone who you can easily talk to. The most important part of any type of relationship is communication. If you cannot communicate effectively with your partner, your relationship will probably not go far.
Start by first talking and later making friends with the person you think is special. Most people don't like to jump straight into a relationship, especially girls. Find a reason to talk to the person. Make sure that they want to talk to you. Just talk about something that keeps the conversation going.
Be yourself and don't lie just to get to a special person's heart. If they find out later and you're in the middle of a deep relationship or maybe a time when you really need that person, they will leave for good.
Let the person know that you like them. Beyond the cheesy sending a note through a friend, talk to them about something you both have in common. School, parents, teachers, vacations, etc. Anything besides a relationship should be fairly safe territory.
Flirt. Flirting is a fine activity if you are interested in people who like to flirt. The social and playful activity certainly draws attention and can lead to a relationship. If it is not you, then don't bother, it is better to be yourself.
Take things slowly. Don't be too needy. They'll think you're just an annoying friend and you probably don't want them to think that. That special person might actually ask you over or on a date, which doesn't necessarily mean that he or she is into you. Give it time and things could work out. Once you have established 'first contact', remember not to squeeze the person. Try to continue doing your normal routine, with them in mind, rather than changing your whole life around them. Hopefully they will want to have a relationship with YOU, not a clone of themselves or a tag along.
