The hot streak

Researchers analyzed the career-long performance of more than 20,000 scientists, 3,000 artists, and 6,000 filmmakers. 

They found and confirmed the existence of a "hot streak" in one's mid-career - a multiyear where there are a series of successful outcomes within a finite period. 

Between 80% to 91% of people analyzed were likely to have at least one hot streak, while a third had two hot streaks.
