A book I need to read

I’ve never read Anne Frank’s diary. After reading the quotation below, I think I’ve been missing someone who was a prodigy. I mean, how many 14-year-olds write like this?:

“I am the best and sharpest critic of my own work. I know myself what is and what is not well written. Anyone who doesn’t write doesn’t know how wonderful it is; I used to bemoan the fact that I couldn’t draw at all, but now I am more than happy that I can at least write. And if I haven’t any talent for writing books or newspaper articles, well, then I can always write for myself.”

Anne Frank, “I Want to Write” (1944), in The Living Language 386, 387 (Linda A. Morris et al. eds., 1984). (Source: Garner’s Usage Tip of the Day.)
