Different people are most clear-headed and productive at different times during the day. I get that.
But there’s something powerful about doing your most meaningful work first thing in the morning. Before you go to your day job, for example. It’s great when you know for the rest of the day that your purpose work is done for now. And you’re excited to go to sleep and wake up early to get it done the next day.
Whatever feels most significant to you, doing it early in the day is probably best. It’s been really inspiring me lately.
