From The World is Flat, Thomas L. Friedman
Every morning in Africa, a gazelle wakes up.
It knows it must run faster than the fastes lion or it will be killed.
Every morning a lion wakes up.
It knows it must outrun the slowest gazelle or it will starve to death.
It doesn’t matter whether you are a lion or a gazelle.
When the sun comes up, you better start running.
