I think there are limits. I compare it to athletics. With hard work I can double my bench press but there are people who can bench even more without ever training. If these people work hard in addition they can perform on a level that's not achievable for most of us.

I think it's the same for sales or a lot of other professions. People with talent can go much further.

I think this is true too, just that with sales unlike athletics, the field is more inclusive (e.g. specialized knowledge in the product field may be more important than absolute speech skills), and also higher populated leading to there being more positions for people who are merely above average, rather than superhuman.
