When Alex Honnold and Tommy Caldwell reached the top of Yosemite's El Capitan in on June 6, they realized they had broken the speed record for climbing it. When they scaled the 3,000 foot vertical nose route they didn't just break the record, they shattered it. They did it in under 2 hours, which was previously thought to be impossible. In climbing this feat is up there with Roger Bannister breaking the 4 minute mile barrier, or even as unthinkable as running a sub two hour marathon,

To put this into context, most climbers take several days to complete the climb and spend the night sleeping on the side of El Capitan while suspended from a harness they rig; elite climbers seek to finish in one day. Completing the climb at this record pace was no accident, they trained both physically and mentally in order to do so. 

They used a technique known as "feedback partnering" to ensure that they were constantly learning and adjusting course as needed. Attempting to improving your performance without feedback is like trying to find your way walking in the dark.You may get lucky occasionally, but you typically get lost. 

Honnold shares how trimming inefficiencies is one of the most important things you can do. After every climb Honnold and Caldwell would debrief to discuss what worked, what didn't, and how they could improve the next time. They continually ask each other questions and look for ways to do better be evaluating each other.

You should also find a feedback partner to help you grow. This is a person that you can trust to give you productive guidance and advice on what you can do even better at (your strengths) and where you need to improve (your weaknesses).
