Meditate on this: Hundreds of people ready to quit their day jobs, burn up savings, risk personal reputation, toil 70 hours per week, absorb as much stress as having a baby (believe me, I've done both).... all without identifying even ten measly people actually willing to pay for what they're peddling.
Short-sighted, no?
Great read for any prospective entrepreneur. It's another good start-up sniff test.
