The mistakes that I've done today does not define my whole being. If today is a failure, doesn't mean that tomorrow will be the same. Criticize me today and see me improving tomorrow for everything that happens in me is a part of the learning process.
Today's comedian has a cross to bear that he built himself. A comedian of the older generation did an "act" and he told the audience, "This is my act." Today's comic is not doing an act. The audience assumes he's telling the truth. What is truth today may be a damn lie next week.
