I’ve interviewed hundreds of people who are experts in their field...

When I ask the question: How often do things go according to plan?
Overwhelmingly, the answer I get is 85-95% of the time. Not a single person has ever responded with 100%. Not once.
When you need things to be a certain way to get going, you’re losing that 5-15% window to be durable and make things happen.
That window is where excellence is found.
