How to Act Serious, Emotionless, and Professional

Are you a teenage kid, bullied? Rejected by your peers? Turned down by every girl you were attracted too? Treated like a "loser", "dork" or a joke? This article isn't about improving yourself or being more mature and developing relationships with the school goody goodies. It is an option for those unfortunate few who are hurt constantly by peers, and are sick of being everyone's "fool".
Steps

Lessen your smiles and laughter, this is the single most important step, remember, you can laugh as much as you want over a joke by yourself in a quiet place, in your own mind, or at home, but when a person tells you a joke, or something funny or joyful, don't smile or laugh, but be nice, express your emotions by your words, not by your facial expression.
Girls and bullying: Perhaps you have had girls come up to you and act like they were friendly, (ex. "Hi Fred! how was your day"?), or maybe they giggle at you behind your back? the ones that act as if they think your "cool" and want to hang out with you, but in reality they think your a "dork" and a "loser"? Or are you bullied by other students? if either of these things have happened to you, simply ignore it, don't smile, frown or show any facial expression, ignore them completely and walk away.
Work hard at the tasks you are given, assignments, etc. Being a high achiever will give the impression of "professionalism", another box now ticked, it will also benefit you later in and all throughout your life.
During lunch breaks, recess etc. Retreat to a quiet place, such as the library or somewhere where you are alone.
The stare (the second most important step). Have a serious, "no funny stuff" look on your face whenever you are moving through an area where others are present, refer to the picture below for a better example:
Talk less: Not just meaning listen more, but also, literally, speaking as less as possible during the day. during class, do not speak to anybody unless spoken to by a teacher, and only a teacher.
Speak formally: This is the 3rd most important step, speak clearly, use formal speech and always address teachers, your peers and people by their proper names, unless they specifically ask otherwise.
In class, pay attention and work hard. Choose a desk at the far back of the class, a desk by itself away from your class group, but not so far to the point where you aren't able to pay attention or can't see what the teacher is teaching.
If a girl is giving indications that she likes you, keep with the "cold, hard" attitude, after all, if you have been rejected by every girl you've liked, perhaps you could be making these "indications" up in your own mind. Where as in reality, she isn't giving you a thought.

Tips

This article was not intended for teaching you how to have an entirely new personality, it's simply about giving others the impression that you are this type of person. For what ever reason you want them to think of you that way.

Warnings

You will be avoided by your peers, avoided even further, so be emotionally prepared.
Maybe you want to try out this "new personality" to play hard to get with everybody. perhaps you believe if you sit there with a blank face and look lonely, a kind good looking girl or a friendly guy will come over and offer their friendship to you, be prepared to think again. (it is highly likely you will instead be avoided)
But if you can handle all this, if you are fully prepared to live a lonely school/work life, then by all means, follow these steps, if not, if you really are just trying to be 'harder to get', you might end up just making the situation worse, CONSIDER THIS before trying out the 'new you' tomorrow.
How to Act Like a Dumb Girl
Acting dumb is actually a great way of flirting with boys and men who are not very intelligent, and it will get you lots of attention! Here is how you can achieve the Dumb Girl Attitude!
Steps

Embrace the "dumb blond" stereotype! Blonds may be perfectly intelligent, but the stereotype has power! Dye your hair blond or just keep it the colour that it is!
Trip over many items! There is nothing dumber than tripping over a curb or a basketball or something!
Use exclamation points to end each sentence!
Look dumb! If you are in school then act like you don't know where you are and ask people if the cafeteria is this way - when there is a clear sign with CAFETERIA written on it! Go to the wrong classroom and sit down in someone else's chair. When they find you out, give that sickening smile that everyone hates!
Make silly mistakes all the time!
Support the same politicians your friends think are really cool. That shows you don't think for yourself, which is a hallmark of someone who is not the least bit smart!
Spell easy words wrong and hard words like muttonhead for example, right!
Read nothing but magazines about singers and rap stars, and know every detail about the actresses and actors and reality show stars who are hot right now! That shows that you don't spend your time thinking about important issues. In fact, it makes you look like a complete airhead! Won't everyone be fooled!
Buy things you don't need, like cutesy folders and the latest fashions, especially adorable but uncomfortable shoes!

Tips

A great way to look and act dumb is by laughing a lot - this gets everyone's attention - Don't laugh or act like an alien - that's just weird and not dumb!
Laugh very loudly so everyone can hear you - even if something was not funny!
Wear makeup and jewelry!

Warnings

Some people will think you are thick and that you need to take your head for a wobble. So don't go too over the top.
Don't be dumb - Just act like it!
