Running with Gazelles, Eating with Lions

Every morning in Africa, a gazelle wakes up.
It knows it must run faster than the fastest 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.

(I've learned this African proverb from The World is Flat, a book about globalisation by Thomas L. Friedman)
