I was going to comment on that exact exerpt. To explain and expand further, all university gives you is a breadth of general purpose knowledge. It merely provides a guarantee of a minimum of passion, time invested, and skill. If a degreeless individual can fulfill these minimum breadth and time investments on their own, they've attained the peak of what most college folks will ever. What's more: their motivation and discipline, their curiosity and self-sufficiency will continue accelerating them well beyond the typical college kid in whatever it is they do.
