I think when you're in your 20s, going from adolescence to about 24, I think your life is a series of emotional storms that you have to weather. Life is more emotional at that time, and you're less equipped to deal with what life throws at you. I always think that if you can get past 24, than life really starts at that point.
If you're a lead singer, then you can't afford to be sensitive. On stage, everyone looks at the lead singer, even if you don't want them to - in America, they have those massive follow spots on you all the time; it does your head in. So, if you are a lead singer and you don't toughen up, you're in the wrong job, and you have to get out.
If something I do now sounds like something I did in the past, it's because I played it. I can't help sounding like myself. That's going to happen. The things that I play on guitar that resonate with me are probably the same things that resonated with me when I started playing in Joy Division.
The words that I'm most happy with are the ones that come from my subconscious rather than my conscious. They just feel right. I think that's the same with music, really. If you're doing an album, there's ten or eleven sets of lyrics, so you get to the point of inspiration ten or eleven times - it's difficult.
