You don't really .you just have to push yourself. It will get easier,in time
Act, pretend like you are doing this for a role. After awhile it becomes more natural.
I've been working on that all of my life. I've gotten so that I can make small talk with strangers, speak in public (with an effort). My friends sometimes forget now that I do have to really work at it, because I'm comfortable with them. I have to tell myself constantly that I've a valid point of view, just as much right to express it as anyone else, and mentally shove myself out there. ;)
Work on faking being happy and friendly. After some time it gets easier and more genuine.
imagine you're somebody else.
I suppose it takes courage, like overcoming anything else. Maybe watching others interact and realizing it might not be as perilous as you thought. Trying to be friendly and choosing not to hold someone at bay when they are friendly back and want to interact with you.
i want to know about this tooo any suitable answers will be considered :)
Have a sit down with your self and get reeeeaally comfortable with yourself.
