Challenges motivate

When kids aren't engaged in class, one of the reasons can be that they find the material too easy. Teachers fix this by ramping up the challenge.

The limited resources of a startup and the constant fear of going out of business drive employees to innovate and work around the clock. Steve Jobs used this effect when designing the culture at Apple, famously describing it as the "world's biggest startup."

When faced with a challenge they believe in, people will step up. So in your next strategy meeting, make sure to share with your team the challenges that keep you up at night.
