I just accept that embarrassment is inevitable and move on with my life. The number of times I have embarrassed myself via stuttering is easily in the thousands. Once you've accumulated enough embarrassing moments, they all kind of mesh together and are forever obscured haha. I will say, the most notable ones will always be with you. I still occasionally get flashbacks to when I struggled to say my name in a class of 60 people. Even with these flashbacks I now more so find humor in them rather than dwell on them.
