Do you know your character? I mean, really know them?
Whether you're a writer creating a character, or an actor becoming one, get to know this individual. I mean, really know them. If you don't, then they risk becoming one-dimensional, paper dolls.
Think of the show "Friends." What if the writers, David Crane and Marta Kauffman, and actress Jennifer Aniston only saw Rachel Green as "20-something rich girl?" Rachel would be simple. Basic. Uninteresting. But add in the fact that she's been desperate to get out from under her Daddy's money and have a life of her own, and that she's spoiled, selfish, self-involved, but loving and very insecure, and doesn't know how to do anything herself- now you have a compelling character.
What about Jesse Pinkman from "Breaking Bad?" What if Vince Gilligan and Aaron Paul only saw him as "20-something, 2nd rate drug dealer?" Thanks to Gilligan and Paul, Pinkman wants a friend in Walt, has compassion for him, and he's riddled with fear and loneliness.
And what about Chris Washington, Daniel Kaluuya's character, in "Get Out?" What if Kaluuya and writer Jordan Peele decided to leave him at "20-something black photographer with a white girlfriend?" Chris wouldn't have massive guilt for his mother's death that he was pushing deep inside himself. He wouldn't be a people-pleaser. He wouldn't be afraid of his own success. All of these nuances are what make your character compelling.
And if they don't need therapy for something, you're not done writing them.
