You should always challenge yourself, as an actor, to find the connection between you and the character.
That's another great thing about Think Like a Man picture. The cast is predominantly African-American, but color is never really an issue in the film. It's rarely brought up since, at the end of the day, these guys are going through universal relationship issues that anybody can relate to. So, while the characters like "The non-committer," "The Player," and "The Dreamer" might be recognizable as common stereotypes, color isn't involved.
Honestly, Think Like a Man was the first romantic comedy that I liked. I'd kind of avoided them for awhile because I never felt that any of them were really smart enough. But when I read this script, I genuinely fell in love with the characters, especially my own. So, I just wanted to be a part of it.
