“I do it because I can.”

“And I know I can do this because I went to London on my own, and because I solved the mystery…and I was brave and I wrote a book and that means I can do anything.”

“Why do we writers write? Is it because we have something to say, or is it because we just do? I write because I can, because I just do, and because I am a writer, and so I write.”

“I am only one, but I am one. I cannot do everything, but I can do something. And because I cannot do everything, I will not refuse to do the something that I can do.”

“I am only one, but still I am one. I cannot do everything, but still I can do something; and because I cannot do everything, I will not refuse to do something that I can do.”

“I am only one. But still, I am one. I cannot do everything, but still I can do something. And because I cannot do everything, I will not refuse to do something that I can do.”
