INVINCIBLE
The movie titled 'Invincible' was played by Mark Wahlberg as Vince Papale, a 30-year-old bartender and substitute teacher.
In the beginning of the film, Vince is having difficulty making ends meet between his part-time bartending and low-paying substitute teaching gigs. Due to required school budget cuts, he loses his teaching position and must turn to bartending as a source of income. His wife also departs from him as a result of his lack of progress in life.
When a guy can only tolerate so much failure at once, his father advises him to just let that one go. Vince was inspired to attend to the tryouts by that remark as well as the note his wife left him.
