Knowing Yourself: The True in the False (1996)

Context: (Answering "What made you step up to making your own record?") I felt like I may not get opportunities to do this ever again, so it’s about time—it’s a terrible thing, I think, in life to wait until you’re ready. I have this feeling now that actually no one is ever ready to do anything. There’s almost no such thing as ready. There’s only now. And you may as well do it now. I mean, I say that confidently as if I’m about to go bungee jumping or something—I’m not. I’m not a crazed risk taker. But I do think that, generally speaking, now is as good a time as any.

“Not until I'm ready for you,
Not until I'm ready for you
Can I have it all.”
Song lyrics, The Dreaming (1982)
Context: I don't know why I'm crying.
Am I suspended in Gaffa?
Not until I'm ready for you,
Not until I'm ready for you
Can I have it all.
