A great real-life vignette in a short blog post to show the point.
There is a reason this man is a success: he sees and he acts. He has eyes to see, ears to hear.
You might quibble with my use of the word “success”. Where he lives, what he does for a living, what he believes. These things might not meet your criteria for success.
You would be wrong. You are judging his life by your personal yardstick. And when you do that, you close yourself off to learning new things.
