There is nothing wrong with being unable to learn, but there is a problem with being unwilling to learn. (Bruce Triplehorn, teacher in Brazil and Chad)

Triplehorn’s comment was in response to a quote from American author Brian Herbert who wrote: “The capacity to learn is a gift; the ability to learn is a skill; the willingness to learn is a choice.” Triplehorn also noted the example of older men who had accomplished much in their careers but remained humble and continued to learn.

Let the wise listen and add to their learning. … Instruct the wise and they will be wiser still; teach the righteous and they will add to their learning. Proverbs 1:5; 9:9)
