I started writing much like everybody else, by wanting to be a writer and writing that first sentence. The sentence was 'I love my cat.' in a tiny wire bound girly journal.

The rest of the journey is a long stint of having nothing more worth saying, or doing, except hoping to one day have boobs; and reading, lots and lots and lots of reading.  Then one fateful day, I became ill, and left my job as a computer programmer, never to return.  So I sat down to write, after going through the 72 thousand stages of grieving.  I wrote, as is so often the case for the utterly unemployable.

I butchered the english language until it cried, 'Uncle!' and I saw that it was good.  For me, writing was mostly like reading a really cool book while God dictated it.  So I recommend you read it too.
