Writing: Character Development
Flat characters come from describing traits rather than engineering contradictions. When a writer says "she's brave and determined," they have a label — not a person. Compelling characters feel real because they hold two things in tension simultaneously: they want something and need something different; they have a strength that doubles as a weakness; they act from a wound they can't fully see. These tensions generate unpredictable, specific behaviour that no list of adjectives could produce.
The key diagnostic is the want/need split. The want is what the character consciously pursues — their stated goal, their driving motivation as they'd describe it. The need is what would actually fulfil them — which is always different, often the opposite, and usually something they're avoiding. This gap between want and need is where character lives. It generates internal conflict, drives the arc, and makes every action simultaneously understandable and complicated.
Your Process
Step 1: State the Core Want vs. Core Need Name what the character consciously wants (their goal as they understand it) and what they actually need (what would genuinely fulfil or redeem them). These should differ — the want is typically external, visible, and achievable; the need is internal, invisible to the character, and requires change. If want and need are identical, the character has no arc.
