You make the same mistake as many other in this thread do.<p>You confuse two different things.<p>The question being asked is whether grit is the one trait to rule them all.<p>My answer to that is no it&#x27;s not because most people who are successful have grit (but far from all) and many people who have grit are not successful.<p>And so I introduce another element, luck. Luck is as you say not something you can count on which is the very point here and actually proves both my point but introduces another important one.<p>You can&#x27;t copy someone for success. It&#x27;s not just a matter of having grit it&#x27;s a matter of being lucky and having grit.<p>I don&#x27;t know of any rule or law that implies that something can only be true if you can count on it.<p>A lottery winner who might keep playing again and again and one day win the lottery have grit but it&#x27;s still luck if they win.
