You have to decide what is extraneous and what is central. There is always more to tell. If you want to have a finished product, at some point you have to say "enough."
You evidently do not suffer from "quotation-hunger" as I do! I get all the dictionaries of quotations I can meet with, as I always want to know where a quotation comes from.
We want to be famous as a writer, as a poet, as a painter, as a politician, as a singer, or what you will. Why? Because we really don't love what we are doing. If you loved to sing, or to paint, or to write poems, if you really loved it you would not be concerned with whether you are famous or not.
So I analyzed that and decided I didn't want to be the president during a depression greater than the Great Depression, or the beginning of a depression greater than the Great Depression.
