Input: Billionaire LinkedIn founder and Greylock investor  Reid Hoffman  believes that successful people need to hone the skill of "unlearning."
In his journey to becoming one of Silicon Valley's most influential entrepreneurs and investors   LinkedIn cofounder and Greylock partner Reid Hoffman  has seen the full scale of success  failure  and everything in between.
 He 's both observed and mentored founders like Facebook's Mark Zuckerberg from  their  professional infancy into the heads of world-changing companies.  He 's personally dabbled in managing  investing  teaching  and even political organizing.
 His  career has taught  him  there's a danger all successful people face   he  explained on a recent episode of  his  podcast "Masters of Scale."
"People tend to take pleasure in their mastery of a given field "  he  said. "They go  'I've learned this  and now this is what will differentiate me from other people for all time.'"
 He  continued: "One of the things that I tell people is that success imprints more strongly than failure. And it does so because as you've succeeded  it's like  I've learned this tool. And so  this tool must be right. And so  I just keep applying it  and even as the train comes off the tracks  because part of what happens is  you know  markets change  competitors change  industries change. You change."
