No doubt, a young man, fresh from the bloom of youth, can accomplish great things.
A great general at 20? Sure. But at 20 (or 23), it is unlikely yet that ANYONE is a great judge. And, living in the sewer that is Washington, DC, it seems very unlikely that a youth of 23 would not become bent by the cesspool of evil in which he works and lives by the time he was 43. And then, he might serve till 83.
Anything is possible, but it is imprudent to expect near-miracles.
