Here I have a proverb that I got from my laptop wallpaper. I think it has a great meaning 

 

Every morning in Africa, 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.
