What according to the writer, did his experience as an Everester teach him?

According to the writer, the experience of climbing the summit changes one completely. It helps in experiencing the summit within oneself. One needs to climb that summit in order to get a fuller knowledge of oneself. Therefore, the physical act of climbing the summit of a mountain is akin to the act of climbing the mountain within.

As an Everester, the writer feels that the experience provided him with the inspiration and courage to face the ordeals of life in a resolute manner. The conquest of the Everest as well as the inner summit was in all a worthwhile experience for the writer.
