I have two shortcuts for finding topics you're passionate about:The problems that bug you — To identify your strong opinions, consume other people's opinions (via Twitter, editorials, and conversations) and note when you strongly disagree with them. Then sit yourself down, crack open a laptop, and argue your position while you feel the drive.The fun stories you tell — Readers love being privy to vulnerable stories from your life. Take a story you'd excitedly tell a best friend over dinner and write it down with as many cliffhangers as possible.
