Accept it and can play with techniques along the way but not beat yourself up over anything.  I had techniques that didn't work at first, then began helping on the easier things, then the more difficult things became easier as I cared less and less and eventually techniques became a secondary fallback rather than the answer.  If a technique could really override all stuttering under any pressure i think it would be considered a cure and yet no one can agree to anything so if it can't be easily replicated...
