Esto ya se habia comentado como posible factor importante de q reznor este tan "hiperactivo" en esta ultima epoca. Al parecer mas de uno teniamos razon:

Reznor Finds Creativity In Sobriety
After struggling for years with addiction, Trent Reznor got clean and sober a few years back and released 2005's 'With Teeth'. While Nine Inch Nails fans are used to waiting almost five years between full albums from the band, here comes Year Zero just about two years later. Reznor recently spoke to Gigwise about his current state of mind:

"I can see now with pretty much crystal clear clarity that that aspect had governed my life. I had made writing out to be a terrifying prospect filled with pain and failure and some things that I dreaded doing because I’ve always lacked self-confidence and every other thing," he said, while on tour in Europe. "By the end of my run with drugs I’d also realized that my brain wasn’t functioning right and I’d lost the power to really concentrate – it really made my art suffer, which made me feel worse, which made me want to get high and you know, that cycle starts up."
