For the umpteenth time, one is not a writer unless one is earning a living from it. One is not a doctor until one gets the qualification and works as a doctor. One is not a ballet dancer until one is dancing professionally. One is not a lawyer until one passes the examinations and practices law.
The designation of 'writer' depends strictly on whether one earns a living as a writer or not. The idiot who told people that one was a writer just because one wanted to write or wrote something is the brain (?) chld of Julia Cameron in An Artist's Way. Complete garbage.
