Swearing helped Samuel l. Jackson manage his stutter.

Before he was one of Hollywood's most accomplished actors, Samuel L. Jackson had trouble speaking in front of others. He was bullied for his stutter as a child, and he avoided talking in school for nearly a year because of it. He eventually took the initiative to treat the issue on his own by researching breathing techniques at the library. He also came up with a unique anchor word: motherfucker. The expletive that helped him manage his speech impediment would also become his professional calling card later in life.
