Hello
I've done something on a very small level - I wrote a self-help book for victims of child abuse, which after 2 years with an agent but no deal, I published myself. I also got a blog to support it and (am supposed to) post daily on twitter, which works when you work it ie, books get sold and money comes to me.
Now that's done, I have started my first novel. I gather that around 10 novels online = a part time salary. I've a long way to go obviously!
I have part-time work which I rely on and I have to live frugally.
BUT - I couldn't go on as I was doing. I was burnt out working for a charity in London, huge caseload, never ending cycle that was unrelenting. I also used to look at people who'd started their own thing and wish I had the freedom, the drive, the pride of having made something of my own to give the world.
In retrospect, I am proud of the book but sick of the subject - as a survivor, it harms me to constantly bang on about it and be in the forefront of all the shit news and events that just keep tumbling out.
Writing the novel is pure joy - I mean you just make it up!! I feel I am moving past my past in doing this, moving to a better place that is lighter.
I feel proud every time I sell a book thro meeting someone and it coming up in conversation. I feel proud every month when I think what I can buy with the proceeds.
Working part time / for myself however can be a mixed bag. Why get up in the morning? Why not just stay in bed and work from there? It's not been the springing out of bed with joy experience that I'd thought it would be...
And I am very far from making a living from it - but that's what the future is for.....
I wish you luck tho. Go for it. If you want to, see how far you can get.
