Why isn't it like practicing the trapeze with a net but
going without a net when performing for a big circus?

Why isn't it like using training wheels when learning to
ride bicycle but getting rid of them once you've got the
idea down?

Or like using a map when you get to a new city but gradually
stop as you know the place?
