I attended a few Toastmasters meetings as a Boy Scout while working on the public speaking merit badge, and I’ve had some experience at public speaking over the years. You’re right, most of us don’t entirely get over those tics, but with practice it’s possible to keep them mostly under control. And of course, the only way to get better is to practice, practice, practice, so there will be plenty of room for flawed speakers on the stage. ;-) Thank you for reading and commenting!
