Absolutly.
The first sales job I ever had I learned how to do my canned sales pitch and then overcome objections. In fact, every shift started with the group doing role playing where we would overcome objections and convince each other. I guess this was like warming up before the game.
I was one of the most successful salesmen in this company every month. However, I never wasted my time trying to overcome any objections. At the time, I didn't recognize why I was successful. Looking back on it I realize that it was because I didn't waste my time and energy on people that didn't want what I was selling. Instead I moved on to the next person and ended up finding a lot of people that didn't need convinced.
