Stendhal—I thought

So...there's this thought floating around in my head that Stendhal (Le Rouge et le Noire, that guy) said or, more likely, wrote something along the lines of "if you want to be a writer, write two pages a day—whatever it is, just write".

Of course I cannot find this attributed to him anywhere. All I find are annoying advice fora that tell you to write every day. So, dear reader(s), if you exist: help a brother out? Did I make this up? Did the man never say anything of the sort?

God's only excuse is that he does not exist.
