it's true... I also used to really hate answering the phone, coz I always felt that I made an idiot out of myself. But, the more I do it, the easier it becomes, and the less afraid I feel. I still dislike picking up the phone but I can do it :]
Also, I used to hate doing things like ordering coffee or asking staff members at the shops for help, but the more I made myself do these things, the easier it's become.
