Crafting characters that readers will connect to is every writer’s goal and dozens (hundreds?) of methods exist to achieve it: deep backstory planning, character profile sheets, questionnaires, etc.
Regardless of the roadmap a writer uses, writing an authentic character boils down to one important action: intentionally drawing from the real world, and specifically, the human experience.
The human experience is powerful, an emotional tidal wave that holds us in thrall. We understand it, relate to it, and live it. This is why, even when a character faces a challenge, barrier, or struggle that readers have not experienced in the real world, they can imagine it and place themselves within the folds of the character’s viewpoint.
