In my previous Side Hustle Spark, Guy Kawasaki warned entrepreneurs against naysaying bozos.

Here are a few of my favorite naysayer lines. [You may have run across some or all of these, but reminders still carry lots of value.]

“Two years from now, spam will be solved.”
— Bill Gates, founder of Microsoft, 2004

“Apple is already dead.”
— Nathan Myhrvold, former Microsoft CTO, 1997

“But I predict the Internet will soon go spectacularly supernova and in 1996 catastrophically collapse.”
— Robert Metcalfe, founder of 3Com, 1995
