From Seth Godin’s Startup School:
So the first thing about the duck is that there are a lot of people who spend their time getting all their ducks in a row. … If you want to be a neurosurgeon, you spend 15 years of your life getting your ducks in a row and one day somebody says “Now you’re a neurosurgeon.” But if you’re an entrepreneur, you’re an entrepreneur. Immediately. … Along the way you can collect more ducks and get them in a row … You’ve got to do something with the duck.
