Some quotes that I've used on this blog in the past...

They say, "Sure, we need change."
I say we need revolution now.

They say, "We can't handle this much change."
I say, "Your job and career are in jeopardy; what other options do you have?"

They say, "Times are changing."
I say, "Everything has already changed. Tomorrow is the first day of your revolution . . . or you're toast."

They say I'm extreme.
I say I'm a realist.
