A quote on young men

This is from G.K. Chesterton, and for some reason it makes me think of James Potter and his friends:

"The more sincere and passionate and even headstrong a lad is the more certain he is to be conventional. The bolder and freer he seems the more the traditions of the college or the rules of the club will hold him with their gyves of gossamer; and the less afraid he is of his enemies, the more cravenly he will be afraid of his friends."
