I also worked in a Call Centre with a stutter, which at the time caused me a lot of stress. Not sure how, but over time, I’ve gone into more and more speaking roles, like training classes and speaking to large groups, which years ago the thought would strike fear into me. I really do think, over time, not only the stutter gets better or goes away in my case, but you realise it is not that important, people generally care about more important things in life.
