Show Them It's First Class

I am not a good salesperson. I can never talk someone down to buy something. So it's far from my qualification to advise someone in this field. But a customer, who is doing this job, is having big trouble with his way of thinking. He keeps assuming that his work is not good enough, so his customer might give him a lot of trouble. It's just so wrong.

Out of nowhere, I came up with some advice. "You can't let yourself do that, you know? What you have in your hand now is A FIRST CLASS work, don't walk and talk like it's Not. If you only have half the confidence that you are submitting the first class work, don't expect that your customer will think of it any higher than that. If you speak with your voice shaking, your customer might think there's really something wrong with your work, no matter how good it is. They'll find the reason why you are not confident and find fault in your work. That's psychology, man. You gotta learn that. You are dealing with another human, who have errors, who are careless too, so if you are slack a bit, forgive yourself. You can still bring with you this first class work and everyone will like it because it's that damn good."

There are things you don't learn in classroom. You learn from meeting with people. You can't help but pick a bit of lesson from everyone and the next thing, you know how to use psychology to get the better side of them. 

That's how they know that you might not do it perfectly, but they will still like it. The next time this guy comes, I will know if he learns it or not. I'm sure sooner or later, he will...:))
