We've got a bunch of good quotes on our shop wall,
such as these.
A few of my other favorites:
"Ideas are cheap. Solutions are priceless" ~Jim Zondag
"The world is run by those who show up" (I don't know the author)
"When you have no fear of embarrassment, a whole world of new possibilities opens up to you." - Jim Zondag
At my summer internship, I worked with a very smart guy who gave me this advice:
"In God we trust, all others bring data".
He acknowledged that it was not his quote, but I don't know who's quote that is.
