But what if the the idea changes, as it so often does?

So, why not just write it at the end?

If i write it at the beginning, i might also have to write it at the end; a write and a possible rewrite. If i write it at the end, there is only one write (and no possible rewrite).

Seems more efficient to me to write it at the end.
