For Example: Emma Stone, Prince Harry, Ryan Reynolds (he kinda gets an asterisk thought), Selena Gomez, Kim Basinger, Missy Elliott, Adele, Severide (off Chicago Fire) , Megan Thee Stallion, and Stephen Colbert to name a few. Why enter in or try to get in a job where you know your anxiety disorder is going to get to you and try to repress it? Why not choose a different job?
You could look at it as they have an alter ego (the character) to stand up and not be that person, that worrier. A form of therapy by dissociation possibly.
Like Ryan Reynolds once said he gets in the character of DeadPool to get through interviews.
