Where does Rene Saldana get his ideas for writing?

Here’s a ansewer from a QnA of him

“I’m really very loosey-goosey when it comes to a “routine.” I don’t challenge myself to write X number of words per day. I don’t have a place where I have to be sitting to be able to work. I don’t write exclusively on a laptop. I’ll use a notebook sometimes, if that’s what I’ve got handy. The stereotypical napkin if that’s it. The only thing I try to keep on routine is working at night once my three boys and my wife have gone to bed. Every night.”
