Yep totally agree. Stuttering can take up cognitive bandwidth if your always thinking about it, so best not to worry what other ppl think. It's easier said than done though, since sometimes it can really get to you. Like say for example you prepared really hard for an interview and you know your stuff, but when it comes to the interview, you can barely string together a sentence or explain to the interview what's happening since the blocks are so frequent. That can really get you since interview can be hard to come by and you put a lot of time into preparing.
