I trust science
In general, scientists are motivated in their work by curiosity about the world and how it works. Behavioural science is the branch of science that deals primarily with human interaction and has a fundamental connection to sales, as salespersons ask a lot of questions, experiment and interact with buyers.

Increased self-awareness
Improved emotional intelligence
Improved agility
Reduced social anxiety
Reduced fear in managing difficult conversations
Improved ability to assess challenges and opportunities objectively
