Read this today and thought it could apply to much more than writers and writing.
Many young writers give me a pain when they complain about how hard writing is and how tough it is to make a living out of it. They talk too much, bellyache too much. Of course everyone knows that good writing is the most difficult of all occupations; but it is a self-imposed one. Writers should be writing instead of talking.
