"Somewhere in Africa, a gazelle wakes up at the break of dawn.
It knows it must outrun the fastest lion or it will be killed.
Somewhere else in Africa, a lion wakes up at the break of dawn.
It knows it must run faster than the slowest gazelle, or it will starve.
Now it doesn't matter whether you're the lion or the gazelle,
What matters is when the sun comes up, you'd better be running."
--Maurice Greene
