I love this quote, one of my favourites. I get something like this each day via email from http://www.justsell.com
"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 had better be running."
