How did you get to the edge?
Maybe you recognize yourself in this scenario. You wake up. You think about the day ahead. You realize that if everything goes at least 95% right, you will be okay. You will manage.
If something dips below the 95% okay, you will be doomed.
When there is almost no ground to stand on between two extremes, you know you have found the edge.
Think about a time you found that edge, a day when you were almost overwhelmed by everything you had to do. Then look back. How did you get to that edge? Where did the rest of the ground go?
