Want to be a writer? Read this, nothing if not depressing.
Funny how this 'don't do it' always seem to come from regularly working writers! Yes, it's hard, financially, emotionally, mentally, possibly even spiritually, but........ but what? I don't know. If you need to write then you just will, regardless. But I do have to agree on the 'don't give up the day job' thing. Terry Pratchett, apparently, didn't give up his job as a Press Officer until he had published seven novels!
