What does Rudyard Kipling mean when he says triumph and disaster are the same in his poem if?

In the poem "If" by Rudyard Kipling, he suggests that one should remain composed and humble in the face of both success (triumph) and failure (disaster), recognizing that these are transient aspects of life. By treating both outcomes with equanimity and maintaining a balanced perspective, one can navigate life's ups and downs with grace and resilience.
