This document is an introduction to the book "You Can Sell" by Shiv Khera. It discusses how selling can be one of the highest paid professions if done through commission-based sales. The author recounts how he accidentally got into selling by doing door-to-door demonstrations of vacuum cleaners for $5 per demo. He was naive at first by thinking he just had to do the demo and not sell. The introduction emphasizes that in life, results are rewarded, not just efforts, and that good salespeople are goal-driven and in control of their own destiny through commission-based compensation.
