Effectively communicating with the prospect $/$ customer is obviously critical to your success as a salesperson. As a rule$-$of$-$thumb, what percentage of you talking vs$.$ the prospect $/$ customer talking did the Text indicate is optimal:

Question $43$ options:

$50\%$ you $/50\%$ them

$60\%$ you $/40\%$ them

$95\%$ you $/5\%$ them

$80\%$ them $/20\%$ you

there is no "optimal" ratio because every sales call is unique
