How important is it for Artists to to explain thier process ?

As a seascape painter I sometimes have been asked " how do you do that? If I explain the whole thing I think that by that time the person would be thoroughly bored and would probably lose interest in the whole thing,
I remember one time I was looking at at very large photograph that was so beautifully composed and the colors were exquisite, I had to ask the photographer about it. By the time he explained all the equipment he used and the printing process in making it , I was so bored and actually kind of frustrated, because all I really wanted to know is why he chose that angle and what moved him to take the photo in the first place. It's kind of like, if you brought your car in to get repaired, do you really want to know how the mechanic did it ?
So in this painting above I will say to you that I painted it because this is my local beach that I go to and surfed this wave many times. I know the the currents here, and I how it feels to be paddling up to this wave when you are out there. So, when I am painting on the beach like this my mind is really out there in the water and I want to share that feeling with you.
