It really is mind over matter. No excuses. Just do it!
I have actually used both, so I am not sure. :) I am the worse person with phrases. Until a year ago, I was saying "play it by year". And that is just one of the many I have discovered that I say wrong. :)
Hah! That's funny, Sarah. I've always said, "for all intensive purposes" instead of "for all intents and purposes."
The American Heritage Dictionary proposes the original phrase was actually "butt naked." The phrase was then cleaned up to "buck naked" so it could be used in polite company.So I guess it depends on whether you feel like being polite or not.
I've always used buck.
I've always used buck, too, but I tend to screw these kinds of things up.
