  2. Courage is a choice and comes down to pain tolerance.
  3. Startup life gets romanticized, but most of it is hearing no.

  5. Views of new tech swing wildly, like social media going from silly to 'the worst'.

What does Marc Andreessen say it takes to be a founder?

Intelligence, passion and courage. He says the first two are traits but courage is a choice, because it's really about pain tolerance: how many times you're willing to get punched in the face before you quit. Most of a founder's life, he says, is people telling you no.
