My name is
William, but most people call me
Will (and have for most of my life); maybe I'm biased, but I would still choose
Will. I think
Will is such an awesome name, and wouldn't mind if my full name was actually
Will (but,
William is also cool). In my age group (at least), most people called
William go by
Will, so
Liam would be less common. However, I know more people called
Liam than
Will who are younger than me.
