TOD:
"Everything in moderation" makes the most sense to me, and something I try to live by.
I was in a meeting with some technical writers and they hated "growing the business" because it makes no sense grammatically.
When I was younger, I always thought "for all intents and purposes" was actually "for all intensive purposes" and that made no sense. I was happy to learn the correct saying.
When I was about 20, I used "apropos of nothing" to my then-fiancé and my then-roommate and they laughed and made fun of me because they said no such saying existed. Well, they ate their words years later when Cheryl Crow had her big hit and that phrase was in her song. By the way, I just looked up the word "apropo" to make sure I spelled it right and discovered it's actually "apropos" with an "s". Who would have thought? Isn't "who would have thought?" an interesting saying? Okay, now I'm just rambling. Who do I think I am, Bruce Kimmel?
