The popular definition of tragedy is heavy drama in which everyone is killed in the last act, comedy being light drama in which everyone is married in the last act.
Winter is on my head, but eternal spring is in my heart. The nearer I approach the end, the plainer I hear around me the immortal symphonies of the worlds which invite me. . . . For half a century I have been writing thoughts in prose, verse, history, drama, romance, tradition, satire, ode, and song. I have tried them all, but I feel I have not said a thousandth part of that which is within me. When I go down to the grave, I can say "I have finished my day's work," but I cannot say "I have finished my life's work."

Comedy is more difficult than drama. I think it's really difficult to make someone laugh because people have very different comedic sensibilities. In drama, you can get away with being a great actor and surrounded by great actors and having good writing. But in comedy you have to listen and you have to perform with a certain rhythm, because if you don't, it's like playing a wrong note in the orchestra and you can hear the off key and it will fall flat and you won't get that instant response.
Only in the problem play is there any real drama, because drama is no mere setting up of the camera to nature: it is the presentation in parable of the conflict between Man's will and his environment: in a word, of problem.
