How much is too much...?

Happy New Year, everyone :)!

I know I'm probably a tad late in saying that, but hey, better late than never ;).

I've actually been taking a break from the Internet for a while - to be completely honest, I haven't been in a good place lately and being online has only made things worse, which is why I didn't post for IWSG last week. But this weekend has been the first weekend that I feel ready to face the world again, so it's all good :). One day, I'll write a super long post and bore you all to death with my issues, but for now, I'm back and ready to write!

Anyway, so I had a nice, relaxing break over the Christmas holidays and I barely thought about my book at all - but one day last week, a new idea struck me for my novel. I've been idly wondering for a while if there was any way I could rewrite the beginning of my novel, but tbh, I was pretty happy the way it was and unless inspiration struck, I was happy to keep it as it is.

But then inspiration did strike. And immediately I scribbled down the initial idea, and then I was off - writing down all the possible implications of this new beginning for my novel; would the middle still work? How would it change the overall character? Would it change her relationship with the other characters in the story?

I haven't started writing it yet, but I'm planning to work on it this week and see where it takes me. I love the feeling of once again being super excited about my work, but it also got me thinking....how much rewriting, is too much rewriting? How do you know when to stop? I know that if I rewrite my beginning and don't like it, I can always take it out and put my old one back in - but what if I think of another different way to write it? And then another way? How do you know when to stop?? Is there a writerly sixth sense that simply tells you when you're done - that moment when you write the last word, sit back and think, this is it? Or do writers forever critique their work, and will never be fully happy with it?

As a newcomer to all of this, I'm simply curious to know what other writers do! I know authors could probably spend forever tweaking words here and there, but I'm talking about when you come up with new ideas for your novel - you think you've finished and it's the best it can possibly be, then BAM! Suddenly a new scene, a new chapter or even a new character bursts into your head. What do you do? Do you ignore it? Or do you try it out?

I'd love to hear your thoughts :)!

All the best for the new year, everyone! Let's make it a good one!
