I say 'uh', 'erm', and 'ah' embarrassingly often. I've been trying to cut back on this, especially when giving presentations, because I think it gives the impression of being hesitant and not confident. I have to constantly and consciously think about not saying 'uh' for it to work, but more often than not, I end up forgetting and I end up sprinkling 'uh', 'erm', and 'ah' every other sentence.
Has anyone successfully trained/conditioned/brainwashed themselves to stop saying filler words? How do you do it?
