.38 Special said you've gotta "Hold on Loosely". Princess Leia said "The more you tighten your grip, the more star systems will slip through your fingers."

Pop culture often knows what science has yet to prove. But science has caught up. Edward Deci & Richard Ryan, two leading researchers at the University of Rochester, have demonstrated time and again that humans are more effective when they are doing activities they find interesting and enjoyable.

The more you tighten your grip, the less fun their job becomes. A pay raise might persuade us to work late, but it won't make the job more interesting or enjoyable. But you know how to Hold on Loosely, and we love it when you inspire great action by helping to kindle our own inner spark.
