U can not become a vampire, you are made into one. They have to hunt you down and find you. Try not bathing for a day and eating for a month, they like desperation. Vampires are used as a literary metaphor for a person who destroys all of the relationships he or she becomes involved in. (orginally about VD infested foreigners). Normally a vampire is sexy as **** so it is easy for them to find move from person to person sucking blood. Sucking blood is a metaphor for Sex. Don't get it? Exchaning of the bodily fluids? This is why hot needy people are called "Blood suckers". If u'v ever noticed, the strongest vampires are always the hottest. They feed on other peoples energy to survive, but they are very very entertaining to have around.
People think that that "Twightlight" series is really original. It is not. Joss Whedon fliped the role of the vampiricly bad relationship skills to buffy in the slayer series. It was the first time the vampire boys had to feel all the Pain, Q-Q. Emo. Here's how to write a twighlight book. Take any story about a vampire. Now take each description of the vampire in that story and make it into it's opposite. Four-1 example, Eddie Culligin is the perfect boyfriend. Flawless. *Vampire - FAIL* Vampires can't hold relationships. They have to feed off of like 2-3 people a day just to stay satisfied 2~ Vampire's make a cohesive family unit who enjoy walks in the park while donning full turtlenecks and later change into matching softball gear to go play a quick game in the woods. *V-F* Come on, Vamps are disfuntional, 6 of them sharing less than 6 bathrooms? ~Vampire glitters in sunlight like a bedazzeled human being instead of bursting into flames and burning all the way to hell. ........ This one actually makes me angry. Vampire Don't sleep at night. They are busy having Sex, and then sleep all day. Sunlight hurts.
So there, the moral of the story is you don't want to be a Vampire, you want to be Emo. But its not becuase Emo is the stereotype that most resembles Vampires, Its becuase Goth isnt cool anymore

It’s not practically possible to turn entire to vampire, but you can be like vampire with long teeth and its behavior. If you eat more meat you will have teeth similar to vampire and change your behavior like a vampire.
Last but not least do regular exercise to build your body, and don't forget that you can't be immortal like vampire there is no medicine ate created.
