Yeah it's quite normal for some people. Not so much a psychiatric problem that needs medications, more a personality trait. If your job requires talking to people you'll be training yourself to talk to people more and more. Always have a few topics ready. Like go where makan good, sports, making ends meet (we're ALL financially constrained now) and new places to hang out. Avoid politics and religion. For women just compliment what they're wearing and take it from there haha.
