You may be, but do you need to show it? There is a time to impress people, and a time to sell. So are you able to check your ego? Should you?
Let me be straight. YES. If you have to ask, you need to check it. Here is the deal. People want to feel confident that you know what you are doing, they don’t want to feel stupid helping you do it. So where is the line? Closer than you think.
My Friend Andy Harper and I were talking about this and how the best teachers can adjust the level of their message to the students. Could you explain TCP IP to a 1st grade class so they would understand? Now do it again to a class of College Computer Science majors. Same material, just scaled to ability. I hope you said yes.
If you said no, to either, I recommend you practice. Anything complex can be simplified, and just because it is complex, doesn’t mean it has to be complicated. Try delivering your sales presentation to your wife, your kids, your boss. If you can them all understand, you are ready for customers.
There is no question this is an every day issue for you :).
