Good performance decisions come from a clear vision about what matters.
Simplicity in high performance is not 80/20 like the Pareto principle. ( '80% of consequences come from 20% of the causes': and try to find your 20%).
This is ineffective simplicity for high performers. Decisions in high performance are in the 50/50 ambiguous zone, and they matter. High performers have system vision. It is their accelerator. Ambiguity solved. The fog cleared.
System sight comes from the feedback of coaches, evidence and critical observers. You cannot see the system you are in because you are in it. You can't see your own eye ball without a mirror.
High performers succeed with complexity. Marginal gains become visible. Others see an overwhelming puzzle with no answers. To the high performer they have their anchor, their rock and the decisions are clear.
As James Clear wrote, 'you don't rise to the level of your goals, you fall to the level of your systems'.
This is trainable. And here lives exceptional performance.
