I recently started a career in sales, and have been doing very well so far. However, I am worried that two of my Signature Themes -- Empathy and Connectedness -- aren't good

Not necessarily. We did find that many salespeople possess both Competition and Achiever in their Signature Themes, but this does not mean that all salespeople have these Signature Themes in common. In fact, the only thing all great salespeople have in common is that their clients come to trust them enough to buy from them. No one will ever trust you if you are trying to sell with a style that's not your own. Empathy and Connectedness can prove to be very powerful sales themes. Properly directed, your Empathy helps you make your clients feel heard and understood. Connectedness lets you show your clients how your product or service is part of a much larger picture. This helps you with cross-selling, solution-selling, and simply communicating the far-reaching benefits of what the client is buying. In your case, as ever, the best advice we can offer is "be yourself." If you truly have a talent for sales, the trust -- and the sales -- will come.
