This is completely backwards thinking. If you always avoid embarrassment like it's the plague, how is that ever going to help you? All that does is set you up for a life filled with regret for all the missed opportunities. Get out of this mindset. Happiness is not giving a shit about stuttering. The only way to start not giving a shit is to do the hard things you desperately want to avoid. I can promise you this - your advice will definitely only make your life worse. Do the hard things and be happy.
