If you want impact, only pick a few subjects that matter a lot to you. Your sentences should be punchy and memorable. People only remember one thing. You have to direct them to the one thing you want to remember.
From "how to create your personal brand",
It’s a similar situation with your personal brand. You need to think through how to communicate it or it won’t be useful.
Here’s the best way to work through that quickly:
1) Pull up something that can record audio on your computer or phone.
2) Literally record yourself talking about each of your 4 to 5 qualities, why they are important, why other people should think they’re important, and examples that would show the world you have them.
3) Ramble on and on until your ideas start solidifying. Talk until it starts feeling more comfortable and natural to talk about them.
4) Once you start feeling comfortable with what you’re saying, stop recording, and listen to it.
5) Write down the most compelling things you said – the things you think are the smartest, most eloquent things you said about yourself.
6) Condense the best stuff into three sentences that emphasize your primary quality while including the others. (This is your “elevator statement” for the purpose of this exercise).
