AnonymousI think that it helps to keep notes as some of the processes which we work through and some of the lessons which we learn are very deep and complicated and it is too much to ask anyone to retain all of these thoughts and feelings; what you will find with doing any exercise like this is that your thought processes and your writing becomes much more interesting and complex in its nature, so that you are improving your creative skills by making yourself confront ambiguity and changes. This is very helpful in itself and worth doing.
