Imagine two people resisting a cigarette. The first says, "No thanks, I'm trying to quit." The second says, "No thanks, I'm not a smoker." It's a small difference, but it shifts the entire dynamic.
Every Action is a Vote
Your habits are how you embody your identity. Every time you write a page, you are a writer. Every time you start a workout, you are an athlete.
You don't need to be perfect. You just need to cast a majority of votes for the person you want to be. Behavior change is really identity change.
