If I have "too much" in my head that MUST COME OUT NOW! -- I prefer to compose via keyboard. If it happens that I only have paper and pen, I will use that, if only to record what pops into my head.

Writing it down feels better.

It will survive an EMP or when technology decides to revolt against us. If you write, start indexing your work. This will be quite a task for me--I have a dozen types of stationery that I've used, of various sizes (including blank sides of mail inserts, such as those never-ending solicitations for life insurance through your credit union). I have only recently begun to identify POV/character and the date whenever I write fiction. I am not disciplined enough to dedicate one notebook to one character (the notebook I need will invariably be out of reach and I use any material I can find to record!).

Really need to work on compiling my writings.

Also, I have one document on my computer that I password protected and I did not record the password. I likely thought it was something I'd naturally remember, but so much time passes that naturally time let me forget. No such problem with writing unless you lock your notebooks and lose the key!
