Here's what author John Steinbeck says about feeling overwhelmed:
"When I face the desolate impossibility of writing five hundred
pages a sick sense of failure falls on me and I know I can never do
it. This happens every time. Then gradually I write one page and
then another. One day's work is all I can permit myself to
contemplate and I eliminate the possibility of ever finishing."
John Steinbeck, Travels with Charlie
