The couple of hours a day will be much better spent with photography than with a word processor.
More and more I realise that the opposite is true. The document and the picture go hand in hand. Unless we are just trying to make nice looking pictures and trying to manifest somehow our vision, concept, art, or philosophy we need to write. I learned a tremendous amount reading Diane Arbus' Revelations. Her writing is as intriguing as her photographs and without it we would all be lost in postulation about what she was doing. I also read John Blakemore's book and again, it's philosophy first, pictures second.
Writing helps formulate and brings ideas to life, literally, like characters, they'll write themselves.
If any of your work has any concept behind it, if there is any thread woven into the fabric of your work, if there is any conversation between the younger self and the present self (and there is!) then you need to create the lineage, not only for yourself, but so that others who find it can decipher the code.
One thing about your initial post that struck me was that you said
but I have reached a point where I do not need to ever expose another frame of film that looks like my existing work
Your have answered your own question there. You have two choices; 1. stop making anything that looks like your existing work or 2. print. Imagine a musician saying 'I know every note, every chord and there's nothing else I can do with them'.
You're either making pretty pictures or you're trying to get a piece of your soul born from a sacred place so that it may resonate forever.
Good luck and much strength to you.
