Feel this so much right now. Had an hour long presentation today, was going great during rehearsal but of course that was too good to be true. Had pretty severe stuttering at times throughout the presentation. Think sometimes rehearsing too much actually hurts me, I feel like it puts limits my natural speech patterns and causes a worse stutter. Anyway, like someone else said, what matters is the content of what you are saying, not how you say it. If someone has a problem with that, fuck em.
