Having clarity about what we want and what we don't want is only half the battle. 

Because we all have reasonable clarity on what we want and what we don't want.

The real battle is in knowing what combinations of these we will say yes to and what combinations of these we won't.

The real battle is in having clarity about the entire picture, not just in parts.

When we deal in parts, we lose track of the whole picture.

Start with the entirety first and then dive into the parts.
