8 years ago I had joked about replicating my brain into an app that would plan a trip for you, since all my friends said I planned the best trips.
Fast forward to a startup event where we were paired up and had to pitch a random idea. I remembered that one and talked it through with my partner. They asked for volunteers to pitch to the group, and she pushed me up on stage.
People loved the idea. They had to forcefully cut off questions, and I was mobbed afterward. I thought...wow, that's a different response from what I normally get.
