"Talk is cheap, *******,
so, either take the initiative
or shut the **** up and step out of the way."

Or, as my Father always told me:
"**** or get off the ***."

Vis-a-vis:
"Everyone wants to ****,
but nobody wants to be ******."

Sort of like:
"Everyone wants a revolution,
but nobody wants to do the dishes."

But then again:
"We're all doing what we can."
