Get into the office an hour ahead of the rest of the company.
It gets harder once you have kids (it certainly did for me), but many, maybe even most, of the most successful CEOs I know do this.
Your day as CEO will be full of constant interruptions even just after $1m in ARR. After $10m in ARR, your day will be full of constant meetings. After $20m-$30m in ARR, you won’t have a free moment ever.
The hack is to get in an hour before anyone else.
This is the time to work on the 2–3 things you need to work on, yourself, as CEO.
