DON'T BE FRIENDLY, DON'T BE NICE
do you want respect as a friend, or respect as more like fear? (such as respect you give to a bully)
When you become too friendly with a lot of people in High School this tends to lead to disrespect. How? because once you are close to someone you can make fun of that person and not give them the sort of respect that one gives to non-friends.
If I don't make sense look at this example. You will joke around with friends, they can make fun of you etc, but you can't do that to the guy in class that you don't know well. Why? because you don't know what could happen and you don't know him enough to do that on a friendly basis. Nobody likes to start fights.
Don't let everyone think that you are their friend.
Im not saying you treat people like crap, im saying that you should quit being friendly. No more saying hi to people first time you see them in the day (let them say hi to you), no more treating girls like queens, keep smiles to a minimum, be serious most of the time, less joking around with people, look people in the eye when you talk to them at all times, don't share your secrets with anyone.
Another example is what the DJ Bible says about keeping girls interested by being mysterious and not letting girls know your feelings etc. Think of it as not being too nice,friendly with people in a way to keep a distance from them. Be your own man, have a "independent guy, minds his own business' aura around you.
