The person with 20 years of work experience obviously closes more deals than someone with 3 months of experience.<p>But I think my original point stands. To put it simply&#x2F;mathematically: if you are able to close 10% of your sales calls, then no matter how much you learn, you will never be able to improve than stat by more than 10X in practice. There is no way to close more than 100% of your calls. So there are strong diminishing returns in that respect.
