In an interview with thevinyldistrict, Paul Weller discussed being a mod and said:
"Well, it’s just something that I’m really into, y’know? It’s kind of like any sort of code, philosophy, religion—whatever you want to call it. I think it’s something that once you’re into it, it’s integral to you. It’s really part of your life and the way you think and all that. But the reason why it’s endured so much is because it’s adaptable. I think because every generation comes along and discovers it, and kind of just adapts it and fills it and it becomes something else again, and mutates a little bit, and I think that’s why, really. It’s quite a concise way of living and thought, really.
There’s a famous old Pete Meaden quote that mod means “Clean living under difficult circumstances,” which is very apt, really.
