A little Hemingway in the afternoon

I just started reading Hemingway's 'Death in the Afternoon' and came across this sentence:

However, if I had waited long enough I probably never would have written anything at all since there is a tendency when you really begin to learn something about a thing not to want to write about it but rather to keep on learning about it always and at no time, unless you are very egotistical, which, of course, accounts for many books, will you be able to say: now I know all about this and will write about it.

I think that 'tendency' is also partly why I blog a lot less these days - as I've gotten more aware about the world in general and about the skill involved in writing, I end up spending more time reading others (and sharing a lot of what I read online through Google Reader) while discarding most of my own output as being not very good.
