As the saying goes, necessity is the mother of invention.
Oddly enough, the first person to say that wasn't me. It's was the Greek philosopher, Plato. (But that's neither here nor there.)
Of course, I've had plenty of necessity to lead me to invention. I was always tinkering with things. Who hasn't? Seems you can't throw a quill pen without hitting some problem that needs solving.
The Postal Service was one of the benefactors of my early ingenuity, but I was just first in a long line of problem solvers. Every day, someone somewhere identifies a problem and creates a solution.
I'm not content with things that aren't working and I'll bet you aren't either.
How about you? Have you solved any Postal problems lately? Do you know of any that were solved by someone else? Tell me about it! Comment here and then send an email here.
