Run hard, be strong, think big!

That advice came from Percy Cerutty, an athletics coach from Australia who died in 1975. 

Another admonition comes from an unknown author:

Every morning in Africa, a gazelle wakes up.It knows it must outrun the fastest lion or it will be killed.Every morning in Africa, a lion wakes up.It knows that it must run faster than the slowest gazelle, or it will starve. It doesn’t matter whether you’re a lion or a gazellewhen the sun comes up you’d better be running.

I don't run. I do walk, mostly purposefully from one place to another. But I wouldn't mind watch others run, especially if they limited their wardrobe to running shoes.
