Not so much. It is, on the face of it, redundant, which is the opposite of cancelling itself out.
It’s not even really redundant, though…it’s making a point that is, honestly, pretty transparent, but frequently needs to be said - it is what it is, it isn’t something else, it can’t be something else, so quitcherbitchin and roll with it.
My own…‘Do or do not, there is no try’.
In its original context, it’s perfectly valid - Yoda didn’t have time to try to work with Luke’s learning curve, so he wasn’t giving points for effort. It was do or die, pass or fail, and if Luke failed, by god, he was going to keep doing it until he passed.
Outside of the context of the movie, though…I’ve seen it used two improper ways.
First, the semi-reasonable one: Talking as though everything is a pass/fail situation. No learning, no testing abilities and boundries, no ‘ok, sure, I’ll let you give it a shot’. Not everything is life and death. Not everything should be life and death. There’s a place for ‘try’, and I’m pretty sure Yoda wasn’t saying there wasn’t - just the there and then wasn’t it.
Second, the WTF one: Calling failing to succeed at a bad thing morally equivalent to not trying in the first place. ‘He tried to kill me!’ ‘Do, or do not, there is no try. You’re free to go, sir.’ Pheh.
