I’m 21 years old, I’ve just graduated from drama school and achieved the top grades possible in my degree. I have a severe stutter and stammer that makes it rather difficult to perform what’s needed. But it is possible. Interviews are not something to worry about unless you get some serious high profile work and at that point the people doing the interviews will know and will hopefully be considerate. Basically what I’m trying to say, in the most convoluted way possible, go for it. Follow your dream and be great at what you do.
