You can tell by the first 2 minutes...

When listening back to sales calls, I can usually tell where the conversation will go judging by the first few minutes (following any small talk)...

The dead giveaways are:

1) Tonality / Presence

2) Assertiveness

3) Structure

4) Credibility

5) Management of expectations

Ask yourself how you measure up to each of these points.

How would you score yourself out of 10 across each one?
