When they say success in sports is 90% mental, they are talking mostly about Mental Execution. Mental execution is paramount to performance during competition. Failure to mentally execute usually results in defeat. The athlete might be outmatched physically but with superior mental execution, they will prevail in many cases. Mental execution not only leads to victory, but reflects cognitive development and bolsters both confidence and the desire to continue learning and improving. The pinnacle of mental execution is performing during competition without thinking, being on autopilot. Often, this is described as being in the zone or being in the flow.
