Well, I have to actually cook or do the thing I write about. I am visual, so taking pictures helps. It takes me only an hour or so to write and I write in the morning right after my Tai Chi when I am at my best.
I do let my writing sit until later in the day when I edit and spruce it up.
I publish here the next morning.
If writing was the only thing I had to do I could get more done but I also teach classes and that takes much time.
A friend has about 20 mystery novels published and she gets up before sun-up and writes until she has done 3,000 words and sometimes more.
