The Sages do not consider that making No mistakes is a blessing. They rather believe that the great virtue of man lies in his ability to correct his mistakes and continually to make a new man of himself.
Most people have a mortal dread of making a mistake.
But more often than not, the reason is not a very noble one. It is usually based on the fact that human beings respect the fear of being misunderstood or being ridiculed by others.
Those who are dominated by such a fear seldom do anything except take care of themselves and frequently fail at that.
The more hopeful and persistent you push on despite your mistakes, the better disposed you will be to help others who have made bigger mistakes.
Good nature and good sense must ever join! To err is human, to forgive is divine.
