Can you be humble enough to realize that everyone has something to teach you?

If you happen to be in company with a merchant or a sailor, a farmer or a mechanic, a milk-made or a spinster, lead them into a discourse of the matters of their own peculiar province or profession; for every one knows, or should know, his own business best. In this sense a common mechanic is wiser than a philosopher. By this means you may gain some improvement in knowledge from every one you meet.

-Isaac Watts, The Improvement of the Mind, p. 80

The above quote from Isaac Watts is one of the best pieces of advice that I have ever received. I use it virtually every day of my life, and I cannot tell you how much it has helped me and enriched my existence in this world. It is one of the ways in which we can ‘become as little children.’
