Be always sure you are right - then go ahead.

Throughout the day no time for memorandums now. Go ahead! Liberty and independence forever.

You may all go to Hell, and I will go to Texas.

Be always sure you're right, then go ahead.

Make sure your right, and then go do it.

I am at liberty to vote as my conscience and judgement dictates to be right, without the yoke of any party on me.
