On her website, J K Rowling has a page in which she answers the question, “Do you have tips for others trying to write?”

Ms Rowling says, ” I have to say that I can’t stand lists of ‘must do’s’, whether in life or in writing.
I haven’t got ten rules that guarantee success, although I promise I’d share them if I did. The truth is that I found success by stumbling off alone in a direction most people thought was a dead end, breaking all the 1990s shibboleths about children’s books in the process. Male protagonists are unfashionable. Boarding schools are anathema. No kids book should be longer than 45,000 words.
So forget the ‘must do’s’ and concentrate on the ‘you probably won’t get far withouts’, which are:
Reading
This is especially for younger writers. You can’t be a good writer without being a devoted reader. Reading is the best way of analysing what makes a good book. Notice what works and what doesn’t, what you enjoyed and why. At first you’ll probably imitate your favourite writers, but that’s a good way to learn. After a while, you’ll find your own distinctive voice.
Discipline
Moments of pure inspiration are glorious, but most of a writer’s life is, to adapt the old cliché, about perspiration rather than inspiration. Sometimes you have to write even when the muse isn’t cooperating.
Resilience and humility
These go hand-in-hand, because rejection and criticism are part of a writer’s life. Informed feedback is useful and necessary, but some of the greatest writers were rejected multiple times. Being able to pick yourself up and keep going is invaluable if you’re to survive your work being publicly assessed. The harshest critic is often inside your own head. These days I can usually calm that particular critic down by feeding her a biscuit and giving her a break, although in the early days I sometimes had to take a week off before she’d take a more kindly view of the work in progress. Part of the reason there were seven years between having the idea for Philosopher’s Stone and getting it published, was that I kept putting the manuscript away for months at a time, convinced it was rubbish.
Courage
Fear of failure is the saddest reason on earth not to do what you were meant to do. I finally found the courage to start submitting my first book to agents and publishers at a time when I felt a conspicuous failure. Only then did I decide that I was going to try this one thing that I always suspected I could do, and, if it didn’t work out, well, I’d faced worse and survived.
Ultimately, wouldn’t you rather be the person who actually finished the project you’re dreaming about, rather than the one who talks about ‘always having wanted to’?
Independence
By this, I mean resisting the pressure to think you have to follow all the Top Ten Tips religiously, which these days take the form not just of online lists, but of entire books promising to tell you how to write a bestseller/what you MUST do to be published/how to make a million dollars from writing.
I often recommend a website called Writer Beware (https://accrispin.blogspot.com) to new and aspiring writers. It’s a fantastic resource for anyone who’s trying to decide what might be useful, what’s worth paying for and what should be avoided at all costs. Unfortunately, there are all kinds of scams out there that didn’t exist when I started out, especially online.
Ultimately, in writing as in life, your job is to do the best you can, improving your own inherent limitations where possible, learning as much as you can and accepting that perfect works of art are only slightly less rare than perfect human beings. I’ve often taken comfort from Robert Benchley’s words: ‘It took me fifteen years to discover I had no talent for writing, but I couldn’t give it up, because by that time I was too famous.’”
