I really wasn't scared, either. I was scared of other things, but not clipless. I rode for about a year on flat pedals on an old mountain bike and when I got my first road bike, I got spds. DS took me out at 6 AM on a Sunday and I practiced. I rode around for 3 weeks with just one foot clipped in, but after that, it was totally intuitive. Two years later I switched to Speedplay X2s and I never had an issue.
