A serious writer is not to be confounded with a solemn writer. A serious writer may be a hawk or a buzzard or even a popinjay, but a solemn writer is always a bloody owl.
Happiness in intelligent people is the rarest thing I know.
If you have a success you have it for the wrong reasons. If you become popular it is always because of the worst aspects of your work.
Writing and travel broaden your ass if not your mind and I like to write standing up.
