I recently read a short explanation for why live productions are worth the extra money. I do not remember the author, but the premise was that inherent in any live show lies the tension and risk of failure. When the soloist is all alone, and there is no possibility of hiding a mistake, the price of admission has been validated, and you are on the edge of your seat.
Now take a step back, and think about this from the perspective of the soloist. What would cause a person to step out and take that risk? (I will, for the sake of simplicity, ignore the professional arena for this discussion.)
Why does the church soloist do her special music? Why do the performers in community theater take months out of their busy lives to perform for free? What drives first-time marathon runners to start the race, knowing they might not finish it? Each of these people is risking failure, but for what reward?
The answer might be different for every person that has ever embraced that risk, but the greater question is this: what is keeping you from doing it? Put yourself out there! Tempt fate and risk failure, because in those moments, you just might discover yourself.
