From the NYT Obit of Henri Troyat, the "favorite writer of the French," dead at 95 (link):

'I would read a paragraph of Flaubert out loud and rewrite it from memory,” he explained, “then, by comparing my version with the original, I would try to understand why what I had written was an affront to what I had read.'

Thanks, Larry, who adds: now why didn't I think of that?
