Definitely. I’m 28 now and have been a lecturer for 4 years. I’ve found the only option in life is to live like you don’t stammer. No one cares about it as much as you do. I’m open about it when I meet people. I still stammer but I try my best not to care about (this gets easier with time) The more you answer the phone, talk to strangers, do whatever it is that makes you anxious, the less you will stammer in the long run.
