Reading about writers
When you don't feel like writing, but want to feel like you're writing, you can always read about writing- or about writers.
A recently discovered collection of great little books is 'The Last Interview Series', which collects interviews of deceased authors. In honor of the 20th anniversary of 'Infinite Jest', you can read the David Foster Wallace one (his YouTube interviews with Charlie Rose are cool, as well as a bit disarming- you can sense this brilliant mind ready to burst, uneasy, as he parses out his words to avoid the untrue).
The Hemmingway book is also a great read- making him seem a pompous ass (as portrayed in 'Midnight in Paris'), but also really human, humble, and full of doubt.
