Goals create the constraints that guide us. Flow most easily occurs as you break big goals down to their smallest chunk. If you’re a football team, rather than overly focusing on the goal to win the game, you simplify the focus to the set of downs and even to the specific play.
Rather than trying to win the game, you try to get the touchdown or the next first down. That’s the mile marker.
Focus on the goal right in front of you and do that again and again, knowing these are the critical steps to the overarching goal of winning the game and then the championship.
If you’re a writer, rather than focusing on the completion of the whole book, you simplify the goal to a single chapter, a single illustration, a single page, and a single paragraph.
