I've gotten to the point where anything that takes less time
than it takes to go get a cup of coffee is fast enough. I
used to think fast, elegant programs were required. But
when you are writing one-offs day after day, why bother?
With Starbucks just across the street, I can afford to be
a little loose with a FOR loop.

Cheers,

David

P.S. That said, I just spent the entire weekend re-working
a program I inherited from someone else. It is generally a
good idea to write a program in such a way that someone else
can get it to work in less time than it takes to write the
darn thing from scratch. :-)
