Guys and girls,
DON'T QUIT FACEBOOK. It takes time and energy to build up a facebook presence so don't quit it.
You gotta talk to others so others will talk back to you. Be aggressive (but not needy & creepy).
A friend of mine used to have way less friends than I did.(I used to be quite popular) However, I quit Facebook for a year and to my surprise, he overtook me and have 150 more friends than I do.
Start building your friends network, try to 1 person per day. I don't think it'll be that hard(it's intimidating though but we can do it!).
Unless you have like a million friends, you'll always be jealous of people who have more friends than you do. I have 430 friends but when I look at people with 800 friends, I feel inferior. However, now I just tell myself to f*uck it and suck it up. If I add a person a day, I'll have 800 friends next year.
So guys, it's doable as long as you are willing to stick your neck out and take risks.
