One day at a job forum, I met a recruiter and she adviced me to never tell to recuiters that I stutter, because I need to be confident, my stutter will not impact my job, people will just need to wait 10 more seconds, and that's all. I know that it's a valid point of view, but personnaly, I prefer to bring it. Like for example, if start to work with a new colleagues, and that I stutter a lot (for some people I need an adaptation time). He noticed that I stutter, so I prefer to say to him that I stutter, so we are all clear. I tell something like "sorry for my stutter" (I know that it's not good to apology, but I didn't found something else, if you have an idea don't hesitate to comment :) ) And actually, say it makes me more confident. Every time I bring it, the other person will say something like : "Don't worry, it's not a problem", and more you hear it, more confident you become. Now, when I met someone new, I always remember what the others people told me before, and I became more and more confident.
