I think it just

I think it just has to do with getting older and getting better at what it was I was doing, and that I could take something small and kind of take my time with it. I think actually what that has to do with is I quit drinking. Before that I told myself I could only drink if I was – if I was writing, I had to be drinking. So I was on a timer, because eventually you get too drunk to write.
