Always thought character sheets were a waste of time, but my buddy's trick changed my mind
I was stuck on a detective story for months, couldn't figure out why my main guy felt flat. My friend Mike said, 'Just fill out a dating profile for him, but as his ex.' So I wrote a fake profile from his ex-wife's view, listing his annoying habits and secret fears. It took maybe 20 minutes, but suddenly I knew exactly how he'd react in a tense scene. That one weird trick gave me more depth than pages of backstory. Anyone else got a weird shortcut for fleshing out characters?
My old writing teacher made us do character interviews on cassette tape. It felt silly at first, but hearing their voice out loud fixed a plot hole for me. That audio trick still works better than any outline.
