His stuck moment: Will makes a living as a janitor at M.I.T. but is discovered to be a self-taught mathematical genius. He reluctantly helps an M.I.T. prof with his research, but, afraid of failure and rejection, he sabotages job offers and his new relationship with Skylar, a recent Harvard grad.
He gut checks it: When his friend Chuckie tells him he will be insulted if Will wastes his potential, Will sees how narrow he has made his life.
Unstuck result: By listening to his friend, Will realizes that he wants the opportunities he has denied himself. He decides to start a new life in California, where Skylar has moved to attend Stanford.
