The Case for Optimism and Risk-Takers by Mark Suster @msuster
"Entrepreneurs accept that failure is a possibility but are highly motivated by not letting it happen to them. It can be one of the strongest motivators. Even bigger is the desire to stick one’s middle finger up at all of the people who doubted you all along. Who sat on the sidelines from the comfort of their keyboards risking nothing and criticizing everything."
