Success in Investing : Skill or Luck ?

<Edited with additional info and video clip > Investment Success: Skill or Luck? We always attribute our success in life or any aspect in life ( e.g career development /doing business / investing ) to our skill or performance but does “luck” has any place in these successful events. If we think that skill ( talent ) play a very important role in investing,, then you may find that some very talented or intelligent people fail in investing ( e.g Newton ), and if you think that investing is purely on luck, then we may have a puzzle to explain the success of great investors like Warren Buffett or Peter Lynn and others in beating the markets for multiple years.
