Entrepreneurs are a hearty bunch.  They’re known for persevering when others give up.  But there’s a difference between realistic optimism and stubbornly hitting your head against the wall hoping something will change.

Inc: The Magazine for Growing Companies combed through 30 years of stories to find the ones that best illustrate an entrepreneur overcoming an obstacle where others would have given up.  And, from zappos.com to the 1993 Dallas Cowboys Superbowl victory, many of the results are now taken for granted.  All 30 stories are profiled online.   And to read some unknown stories of resilience, from users of happier.com, visit the Community section, where you can even contribute your own story.
