"I already know that" is a success killing phrase. When you tell yourself or think to yourself that you already know whatever your hearing or learning, you better think again. In my experience those words are the precursor to a humbling experience.
As a professional sales coach, some people will actually unsubscribe from my free email course. Shock of all shocks, right. It doesn't happen often, and when it does I'll sometimes get a comment about how they already know this stuff or they've heard this stuff before.
I immediately know a lot about the other person. I know that the person who just made that comment is an average or below average sales person and that they'll never be a top producer. You see top producers in sales or anything take a different approach.
Do you think Tiger Woods was born with or has developed a body so physically superior to all other humans that it makes him the best golfer in the world? I highly doubt it. What I do believe is that there are subtle differences about Tiger that make him superior: his attitude, his application of techniques, and his commitment to continuous improvement.
Sales is as old as man himself and there aren't really any new ideas. Professional sales coaching helps you to make those subtle differences in your attitude, in your application of proven techniques, and in your commitment to continuous improvement so you can get where you want to be. Coaching can help everyone, but not everyone is coachable.
Instead of telling yourself you already know something ask, "what can I learn from this that I may have overlooked in the past that will help me to get where I want to be"? As you read that if you didn't immediately experience a big difference in how you think about things read it again and again until you get it. Top producers know how to sell, but they work on the fine and subtle details that make all the difference in their results.
