I've plugged it on the forum before, but I genuinely believe it deserves its own topic...

It's a book called "The Artist's Way" by Julia Cameron.

The book at first seems pretty outlandish; it's quite spiritual and honestly I could have given up reading after the first chapter. It talks of a "God," however not in the religious sense, but in the sense of a creative flow of energy which flows through us all.

I know, I was sceptical at first, but I read through it, tried to put a few of it's tips into practise, and it's worked wonders for me. I feel so much more motivated and so much more creative
