What does this quote mean?

“We learn wisdom from failure much more than from success.”

Failure can expose what does not work and force closer observation, turning setbacks into information that uncomplicated success may never reveal.

Source note: Self-Help, Chapter XI, “Self-Culture—Facilities and Difficulties,” Project Gutenberg #935. The passage follows Charles James Fox’s contrast between early success and perseverance after failure, then leads into examples of discoveries and learning produced through mistakes and failed attempts.

“The art of life is more like the wrestler’s art than the dancer’s.”

Life requires readiness for unexpected pressure, closer to maintaining balance in a contest than performing a fully choreographed sequence.

Source note: Meditations, Book VII, section 61, George Long translation; the full sentence emphasizes readiness for sudden and unexpected onsets.

“The courage of the soldiers depends upon the wisdom of the general.”

Leadership affects collective courage because people take greater risks when they trust the judgment guiding the group.

Source note: The Moral Sayings of Publius Syrus, saying 206, D. Lyman Jr. translation (1856).

“If you can meet with Triumph and Disaster And treat those two impostors just the same.”

Success and failure are both temporary conditions, so neither should be allowed to define character completely.

Source note: Poem “If—”; the line pairs triumph and disaster as unstable external outcomes rather than final measures of character.

“The readiness is all.”

The emphasis is not on controlling every outcome but on meeting what comes with preparedness and acceptance.

Source note: Act 5, Scene 2.

“Slow and steady wins the race.”

The moral values sustained progress over bursts of speed that are not matched by attention or follow-through.

Source note: Traditional English moral associated with the fable; wording is later than the ancient Greek tradition.
