Reaching out to people should not be scary

So many people do not feel comfortable reaching out to people. I have increasingly come to believe that if you come across someone whom you can help, can help you, or is simply interesting, you should never hesitate about contacting them. I see job hunters hesitate about calling people, or they call once but do not persevere. Even if you want to talk to someone interesting, it is often astonishing how much they appreciate someone who approaches them.
