There are so many genres out there that finding the one that suits you can be tricky. Look at your bookshelf and look at the titles or the authors. Are there any recurring themes? Do you stick to one specific genre? Do you read authors with a similar style?
You might find that you only like horror for example. That's alright, horror could be your calling. However something I've found is this might not always be the case. I really like reading books with dragons in them, but I found it hard to write a similar novel. Weird right?
If that's the case, have a read of a range of books, not just titles in your favorite genre. You might be pleasantly surprised at what you find! You might also like to write something based on events that have happened in your life and weave in a fictional story-line. That's how my novel, Heartbound, was written!
Take your time over this. Make sure you are fully committed to your selected genre and, most importantly, have fun!
Some say that writer's block is a myth, but I believe it does happen. Some days, the creativity just does not flow!
Writer's block can happen for a number of reasons. Writing does take a lot of energy, especially if you're writing 2000+ words a day, 7 days a week. It's not uncommon for tiredness to creep in and for your creativity to stall after an extended period of writing. Keep yourself hydrated and don't force yourself to write; your talent won't go away!
Your lifestyle can also play a part. Several authors have a job alongside their writing, which can leave them precious little free time to write. Imagine trying to push out 1000 words after a long day in the office! It can be really difficult. And that's alright; an hour here and there can be enough to keep the story ticking along nicely.
The main reason for writer's block, in my opinion, is motivation. Writing can be difficult, and it can be hard to keep motivated if you feel your work is stalling. What is important to remember is that you are not alone; it's natural to feel demotivated, but a quick search on the Internet can provide you with a great deal of resources for getting that motivation back. Or if you're an outgoing person, have a walk around your nearest bookshop and look at the books in your genre. Picture your work among them, and you could well find that the inspiration comes flooding back.
I'm not saying this to put you off, but do not expect instant cash-falls for your work. In the early days, I would strongly recommend keeping a job so you have some income during times of low sales. Think of your job as a contingency plan.
Try, if you can, to find something that can complement your writing. This is not always possible, but try to combine your novel writing skills with another creative role, maybe something to do with magazine writing or blogging. Either way, having another source of income can be valuable in the early stages of your writing career.
Have fun with writing! It can be tricky but seeing something you have written in some kind of printed form is one of the most rewarding experiences you can have.
Even in difficult times, writing can be a great experience and once you have your heart set on being an author, then keep at it!
Best of luck!
