The correlation between pleasure and excellence

Around 1175a, line 30, an interesting claim is made by aristotle. "...since the appropriate pleasure contributes to the growth of the activity. For those who are at-work with pleasure discern each sort of thing better and are more precise about it..." Aristotle is claiming that people who take pleasure in a certain activity, are automatically better at it then those who do not.

In my opinion, this statement is wrong in many cases. The most notably would be athletic achievement, an area that would very much be in effect in Aristotle's time. There are people on this planet that are more skilled at certain activities, naturally, then others. Most people are trained to find something that they are good at and do it for the rest of their life. This is even a very general way of wording Aristotle's philosophy. The issue that Aristotle is not addressing is that fact that these individuals might not find pleasure in the action that they excel at. It is true that people who pursue something with passion and pleasure work harder to attain excellence. The issue is that hard work is sometimes not enough to surpass someone of greater talent.
