Ever passed on an event / opportunity because you were nervous about stuttering?

Ever passed on an event / opportunity because you were nervous about stuttering? I've had a stutter my whole life, and it's never made that much of an impact until I realised I was saying no to opportunities just because of it. One day, I really want to be a motivational speaker for young people who suffer with stuttering and last week I passed on delivering a pitch for my company to a room full of people. I've always had the mentality to not care about it and move along, but, I'm at the start to a successful career and cannot be passing on great opportunities. This is me asking what situations you've passed on that you wished you hadn't and how you feel about it now. Thanks!
