Life as a full time writer

I recently gave up my day job and became a full time writer. It's amazingly exciting getting, but at the same time I'm terrified! 

I'm gradually getting into a routine of writing. Making sure that I don't watch too many episodes of Mad Men or get sucked into reading too many books. I think that's the hardest bit, actually remembering I'm not a lady of leisure and making myself go and sit at my desk. In the same vein, I have to remember that I don't have to work long evenings or weekends on the book now either. I can actually take breaks without feeling guilty. 

I love how my day is punctuated with taking the dog for a walk which gives me time to think about the next stage of my book. I also love how I don't have to stop thinking about my book during the day whilst I do something different. It makes the writing process so much quicker as I'm not having to force myself to remember what I had last written. 

But the big question is - will I become a successful author - or will giving up my day job be the worse mistake I ever made?
