Pick up the nail

This time, it was a staple.

When I'm walking down a road and I spot a nail or a screw or a sharp piece of metal, I always pick it up.

I didn't put it there. It's not my nail. I have no responsibility for it. 

But I do know the consequences of ignoring it. Eventually, it will drive its way into a tire and cause a problem for someone else.

It took me a long time to realize that doing nothing, failing to act, actually causes harm in the world. That realization has changed my approach to things.

It's why I chose a line used by Teddy Roosevelt as my motto: "Do what you can, with what you have, where you are."
