I disagree, personally, because I don't like sticking to one particular tree.
He wasn't talking about forceful sticking to the particular class, he was talking about the reward for dedication to this class and tree.
And if you want a demagogy - fine then. Learning one specialty takes a lot of time and effort, becoming a master in it takes almost entire life (art, composing, writing, etc; and even if you dedicate your whole life to it you still can't say you have mastered it fully because there is always something to learn). And it is just one profession/direction. You are talking about many.
Such talk is just water under bridge.
