When I was 11 years old I was on my second piano teacher. He was also my voice teacher. His name escapes me. I didn't care for him very much and was missing my first piano teacher.
But this teacher had a recital for his students and I was playing a piano piece which happened to be in the key of G. I had been taught from the first to memorize everything, which may be why I'm not that great a sight reader. I have the ability to pay attention to expression, put emotion into my playing. That is easier to do when a piece is memorized. I was motivated to be perfect - that is what I strived for, at any rate.
Anyway, I had this piece perfected, was confident, and was ready for the recital. When it was my turn I began playing and got to a certain point when I blanked out as to what was to come next after I finished a certain phrase. Without missing a beat, or perhaps after waiting a couple of beats which could have been part of the music, I played a few scales and variations of scales in the key of G and ended the piece in a manner that sounded reasonable. Thank you Mr. Valerio, my first teacher who gave me great training and made me learn all the scales and chords stuff.
It gave me the perfect solution. Everybody clapped. No one but my teacher knew the difference. I received the recognition that I sought.
I remember this when I give a presentation; it was a profitable lesson.
When people lead opportunity meetings or just informational meetings in general, they tend to get bogged down in the delivery of the message. In short, they think they have to be perfect to be successful.
What they forget is that the people who are listening, the people who haven't heard the message before, don't know what it is supposed to be. So if you as the message deliverer mess up, the message recipient doesn't know the difference. So don't let it get you down. You don't have to be a superstar.
Besides, if you are perfect, the audience thinks they would have to be perfect, too, and that they couldn't do what you do.
One of my mentors, Tom "Big Al" Schreiter, says that if you're just awful, the prospect thinks they can make a fortune - they can do so much better than you. Of course, the message has to be interesting, not too long, and use the magic sequence of words. You can learn that from the training that Tom does.
So, don't worry about being perfect. The audience doesn't know the difference.
