1. If possible, write on something that is NOT connected to the internet. That way you aren't tempted to check Facebook/Twitter every 5 minutes. Or less.
2. If you are writing on an internet-free laptop, make sure it isn't in the same room as the internet connected one (see 1).
3. If you can't accomplish 1 and 2 for physical/financial reasons, try to allocate yourself specific times of the day to Tweet/update your Facebook. Do not weaken.
4. Unless specific, dickering about on Google is not 'research'.
5. Checking your Amazon rating and sales figures every two days is liable to lead to suicidal feelings. Ditto reading posts from other writers who do this.
6. Ditto reading the 'I wrote a whole novel today - go me!' claims on social media
7. There is no such thing as 'Writer's Block', it is just a posh excuse for not writing.
8. The only way to write a book is to write a book.
9. If you are not constantly awash with doubt/fear/insecurity/self-loathing/envy/anxiety/panic, you probably aren't a writer.
10. Follow your dreams by all means. But make sure you have a day job.
