Hello,
Because the first message was "too long":
The third enthusiastic person, who had the potential but no motivation, was taken in as well, though he'd never pitch for the love of it, but because it'd earn him rewards. In the end, he succeeded, where so many others had failed.
As much as a happy ending would've satisfied the pitching expert, it didn't happen. The fourth person to apply was rejected. He also had the potential, but the lazyness to learn anything was radiating from him, which in the end led to the refusal.
Finally, the worst of all, the fifth apprentice-to-be. Unlike all of the others, he had no potential neither the passion or motivation. All he was looking for, were the possible riches, but he wasn't willing to put any effort towards gaining it. Instant rejection.
