Best-selling author Tim Ferriss loves proving people wrong.
The productivity specialist known for his wildly successful book The 4-Hour Workweek, Ferriss is a pro when it comes to obliterating obstacles that many people consider insurmountable.
During a recent conversation at this year's South by Southwest festival, Ferriss shared some examples of how he's been able to challenge people's notions of what is and isn't possible.
"If I can practice with David Blaine to learn how to go from a 45-second breath hold to three minutes and thirty seconds--and do that with a half hour of training--what are the impossibilities in your life that you should tackle?" he says.
Ferriss also shared his thoughts on how to grow a business during the early days of a startup.
