Try living with your character
When creating a character try this exercise.
As you build a character or characters, you should be able to see them and answer questions about them. As you take action and make choices during the day, do the same with your character.
What do you eat for breakfast? Does your character eat breakfast? What foods do they like or dislike?
Do you wear a particular style of clothes? What does your character WEAR? Why do they like to wear them?
Do you go to the store? Where does your character shop and what do they buy?
What do you do for fun, sports or hobbies? What about your character?
What’s important is NOT what the character did, but what you learned about what you know about the character.
