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."
LinkedIn's Reid Hoffman says successful people need to 'unlearn'

As school leaders try to move on   Joe Paterno  loyalists  including many university trustees  continue to fight over the coachâs role in  his  assistantâs crimes.
In July  Penn Stateâs board of trustees met to discuss the most important issues facing a school system with 99 000 students and a $5.7 billion budget. It took about three hours before someone brought up Jerry Sandusky and  Joe Paterno .

Law enforcement officials  victimsâ lawyers and private investigators â including Louis Freeh  the former FBI director who authored a damning 2012 report that asserted  Paterno âs involvement in a coverup â say the dispute results from stubborn âPaterno-deniers â âJoebotsâ and âtruthers â for whom no evidence will be strong enough to condemn the beloved former football coach.
âThe tragedy of all of this is that it is self-perpetuated and self-inflicted â said Tom Kline  an attorney for one victim. âThey have settled on an endless assault on anyone who dares suggest that there was something that happened that was wrong and that the fault lies at the doorstep of either  Paterno  or the football program.â
But alumni trustees and supporters insist  Paterno  and the school were victims of a rush to judgment that spared other  more culpable organizations â most notably the Second Mile  Sanduskyâs charity for at-risk children â from public scorn. They point to conflicting accounts of the assault at the core of the coverup case  evidence the NCAA may have influenced Freehâs report and doubts about claims  Paterno  ignored assaults as far back as the 1970s.
According to Freeh  in 2001   Paterno  and three university administrators â president Graham Spanier  athletic director Tim Curley and senior vice president Gary Schultz â decided to conceal a report of Sandusky assaulting a boy  to avoid bad publicity for the university and its football team. The men displayed a âcallous and shocking disregard for child victims â Freeh said  as they âempowered Sanduskyâ to abuse boys for another decade.
Freehâs verdict capped an unimaginable downfall for  Paterno   who just eight months before seemed poised to retire as the winningest  most respected coach in the history of college football. In 46 years as head coach  heâd piled up 409 wins and two national championships while professing selflessness and education  fielding teams that wore simple jerseys with no names on the back  his players graduating at rates that outpaced competitors. In the venal world of college football   Paterno  built a reputation as a coach who valued integrity over winning â âSuccess with Honorâ was his motto â and now he stood accused of covering up for a pedophile to protect his public image.
In including  Paterno   Freeh had gone further than prosecutors  who would charge the administrators with crimes but said they did not believe  Paterno  participated. In defending his conclusion  Freeh cited âthe most important evidence in the caseâ: a chain of emails between the three administrators from 2001.

The emails showed the men planned to report Sandusky to child welfare authorities but changed course after Curley met with  Paterno . Instead  they banned Sandusky from bringing children to Penn State and informed the Second Mile of the incident. Sandusky was convicted of assaulting four boys after this incident.
In an email  one trustee urged then-Penn State president Rod Erickson to tear down the statue of  Paterno  outside the stadium  if it would pacify the NCAA.
Eleven days after Freehâs news conference  the NCAA announced that Penn State had entered into a âconsent decree â accepting a $60 million fine and the erasing of all of Paternoâs wins after 1998  the year Sandusky was investigated â but cleared â by Penn State police and a state child welfare agency. Freeh had concluded  Paterno  should have suspected then his assistant was a pedophile.

The lawsuit also produced communications between NCAA staffers and Freehâs team that prompted some alumni to theorize Freeh catered his report â which  by including  Paterno   put the case squarely in the NCAAâs crosshairs â to appeal to a desired client.
The NCAA is only a part of why some alumni feel the school and  Paterno  took a disproportionate share of the blame  Schmidt said  before explaining theories involving a former governor and the Second Mile.

The respiratory illness can also be deadly -- 43 000 people in the United States die from it each year   Dr. Neil Fishman  an infectious disease specialist and associate professor of medicine at the Hospital for the University of Pennsylvania   told Fox News.
For one type of the virus  called Influenza A  the âclassicâ presentation is a sudden onset   Fishman  said. People may first have a headache âmore in the front of your head or behind your eyes â with other symptoms being a fever of at least 103 degrees  chills  sweats and body aches.
"Generally people should start getting vaccinated now "  Fishman  said  and that they should do so by Halloween to Thanksgiving.
These types of drugs can also be used in less serious cases  according to  Fishman . Other flu remedies include getting lots of rest  following a healthy diet and taking Tylenol or Advil   he  said.
âNone of the homeopathic drugs have really been shown to help influenza â  he  said  noting that you should check with a doctor or a pharmacist to see if ânaturalâ products interfere with other medications.
