One of the secrets of good writing is to suggest rather than show . Thanks to the character cards, you will be able to tell everything, and find what to say, by actions and attitudes corresponding to your characters, rather than using faded descriptions.
This is the big difference between:
Gwenaelle spoke with her friend. She was a very pretentious girl who despised men.
and:
She narrowed her eyes and put her cigarette in the corner of her mouth. "Guys, do you what you want. They are so stupid. "She raised her head, and whispered smoke toward an imaginary man.

Thanks to a character sheet of Gwénaëlle, you know that she smokes, in what way, how she speaks, the kind of things she says, you have her face in mind, her attitudes, so you can describe her by her actions .
Use the effects produced on the environment . When the murderer pushes the door of the restaurant, if he is brutal, he will push the door wide, instead of opening it delicately. The cold will then enter the restaurant. We will know who he is in part, by the cold he makes enter the room where he enters.

When someone sits heavily, use the sound produced by his chair rather than saying "he sat down heavily". When it's dark, talk about the light of the street lamps (there are no streetlamps lit in broad daylight, yes potato).
Use dalogue, rather than describe. You prefer "Ah you piss me off!" To "He was very angry".

Create context
In your questions to your characters, you have created multiple situations allowing him to reveal himself. Insert these contexts into your novel, and give body to your content .
The simple question: "What do you eat at breakfast?" Allows a scene in which the hero wakes up, has breakfast, before receiving an important call.
Thoughts and opinions can be revealed in your dialogues with the different protagonists encountered. For example, if your hero has to go to an important place with his friend, make him talk on the way and give his opinion on various elements. See your novel as a series of pretexts to insert your character characteristics and you will get many endearing, interesting, deep scenes.
Your hero is manic? In what situation could we put it regularly that reveals his maniaquerie? When he speaks with someone, he can always want to raise the neck of the person, to recoiffer. And if this person is his teammate, and that she is just the type to let go, and to be messy ...
In the end, your frame is very simple, and can be summarized quickly. What creates the body is your characters, and their way of responding to specific contexts .

Use action verbs rather than state
Count the number of verbs to be and have that are in your last literary production. Yes, huh? Yuck! Replace all that with action verbs, and you'll get a rich, dynamic, and much more lively custom writing .
He was about to leave -> He put on his coat.
He had a decay -> His decayed tooth was torturing him.
The street was sparkling with sunshine -> The sun cast its rays on the sidewalk puddles.
I had received my quarterly newsletter and was afraid my parents would see it -> From the pile of flyers, a small envelope fell on which the terrible words "School Report Card" threatened. I hid it quickly in the pocket of my coat.

Remove
The last step of your novel will be the deletion without souls of your multiple heaviness and redundancy.
Be uncompromising. Your text will gain in strength if you avoid repetitions. You doubt what to delete? Assume that each sentence contains something to delete and ask what.

The most common heaviness:
The exclamation points. Except in your dialogue, and of course, only when the character exclaims, do not put any exclamation point in your novel. Gender zero .
Likewise with parentheses. Parentheses are very unwelcome in a novel. Even in very good novels, I am always struck by the presence of parentheses. Down the parentheses.
Watch for the many qualifying adjectives in the same sentence: "He was very nervous and confused". Bim. One chooses nervous or troubled. And besides, we had said no state verbs. So you will have to find in your cards characters how the character can show his nervousness. "He was biting his thumbnail."
It is often believed that insisting supports our purpose. But we are only weakening it . "She got angry and screamed at the guy." "He devoured and swallowed his chicken leg." "She wanted to become an adventurer, to live passionately, freely, and wildly."

Adverbs.
They can often be replaced by a more specific word. "Really very big = Huge" "Really very small = tiny" "Almost always = often"
When the person speaks normally, use the verb to say. No, not to utter or to decree.
There you go ! You have a method to write a novel. If you follow this technique to the letter, you will have a novel quite correct and publishable.
