2:1 Words of Wisdom

My colleague, Karl Pickering, repeated a real gem of an expression again today, while talking about establishing a new brand:

I like the simplicity of this statement as well as it's 2:1 ratio, which reminds me of my favourite phrase for project planning, the carpenter's proverb:

"Measure twice, cut once."

I'd love to hear some more 2:1 phrases I can bandy about in business meetings (and yes, I have thought of "birds in the hand")...
