My grandmother was probably the first person who I thought was beautiful. She was incredibly stylish, she had big hair, big cars. I was probably 3 years old, but she was like a cartoon character. She'd swoop into our lives with presents and boxes, and she always smelled great and looked great.
You want to try and bring a character to life in an honest a way as you possibly can. It doesn't matter whether he's a doctor, an actor, a car salesman or a captain of a starship. If you can bring truth and honesty to that character, then your audience will believe you.
