we have to go through a period of wanting
When we want to learn something, grow, or get something, we need to go through a period of wanting before we actually learn how to do it or get it.
CWG says that this feeling of wanting is a statement of lack, and pushes the gift away, but we know no other way of going about it. We learn the correct path not by reading or speaking about it, but by learning what it is not (by making mistakes).
