I don't. I have moods.
Some writers have scheduled writing times.
Been there. Done that. Didn't buy the t-shirt because it was too ugly.
I create when the mood strikes me. If you asked Mr. Amazing Dude what this looks like, he'd describe the spark in my eyes that grows into a blazing inferno the longer I sit at my keyboard, frantically trying to capture the story as it rushes through my brain faster than a Japanese bullet train. I may sit for an hour. Sometimes 3 or 4. I may write a page...or maybe 10. I ignore everything else. Eventually my bladder or my stomach dumps a bucket of cold water on the writing fire, bringing me to reality and leaving a couple gleaming embers laying around. I have to nourish these embers. Usually through selected pieces of music, rainy days, art work, nature, scripture, reading other novels, history books, and being in close proximity to Mr. Amazing Dude.

I'm not a morning person, and my creative moods usually don't rouse themselves until at least 9am, often waiting until 7 or 8pm to smack my backside into a chair. I don't like boxing in the creative spirit. Training it, sure, ok, I can do that some.
I also try not to let the very real writing barriers (I apply this word with a strong smear of sarcasm) of working full-time, fighting a chronic illness, and
It's a rather frenzied process. It's not recommended, but it works for me right now.
And regardless of how pragmatic or utilitarian the last statement sounded, I'm really an idealistic softy at core.
Can you tell I'm in a mood? ;-)
