Actually think anybody ever approaches writing any song, I think the song approaches them, truth be told. Usually what happens is that a song arrives and afterwards you say that "I wrote the song," and it's not actually true; they find you, they write themselves.
[Ideas] may not arrive exactly on time, it may not be the most convenient thing for you. For me that happens a very small amount, but if for whatever reason it's not arriving at the moment, it may last forever. Thinking about it won't change any of that.
Some people talk of writer's block - you got all of these ideas but nothing happens. The truth is, there's no such thing as writer's block. It's to the degree that you want to write. The thing is that these things show up whenever they feel like it.
