Few people like to act alone. Most of us prefer someone else be first. After all the first person out takes the brunt of heckling and criticism. Much better to wait to see the reaction of the crowd to the individual.
Most people aren’t willing to try. There is that fear of failure. There is a concern we won’t be very good. We hold back wondering what people might say about us. When we are unwilling to try we miss a great deal. We miss opportunity.
