"The trouble with doing anything right the first time is that nobody
appreciates how difficult it was."

When a team of dedicated individuals makes a commitment to act as
one...  the sky's the limit.

Just because "We've always done it that way" is not necessarily a good
reason to continue to do so...  Grace Hopper, Rear Admiral, United
