Going through a lot of changes right now and two lines are reverberating in my head. I was into punk as a kid, still am I guess, and there's this recurring motif in Rancid tracks: "the secret to a good life is knowing when you're through". Also recently had some words of wisdom I liked from a mate in his mid-sixties: "one door has got to close for another one to open".
