Getting Your Emotions Across
The first stage of creating an elevator pitch is emotion - how do you want people to feel?
Do you want them to get a taste of your personality?
Do you want to hook them with humour?
Do you want to inspire intrigue, or trigger some questions?
Are you looking for a pattern interrupt?
The conversation goes nowhere unless that emotional connection is established - they may hear you but they won't be listening.
You don't win with a 'killer' catchphrase or a clever analogy - it starts with the feels.
