I heard a quote by author Jonathan Franzen today:
"It's doubtful that anyone with an internet connection at his workplace is writing good fiction."
Do you agree?
I think it's a bit strong, but there's certainly truth behind his words.
I admit I can be prone to distraction and the internet is a huge one. I sometime use a computer program to block all websites for a certain amount of time to help me focus on writing.
If you're interested, I use Stay Focussed, a Google Chrome add-on. You can also use it to block only certain websites, to block everything but certain websites, or to give yourself only 5 or 10 minutes per day on time-suckers.
When I'm suffering from writer's block, I like to work on paper. Sometimes I'll send my current document to my Kindle, where I can read it for reference if I need to but can't edit. I have to do everything by hand and though it takes longer, it often gets me unstuck.
As for being influenced by other people, other ideas, other opinions...today's constant flood of input can dilute your own style and make you doubt what is your own idea and what is not, but you can also use it to gain inspiration and deeper understanding of the human race and the world we live in. Just try to be aware of which way you're using the information overload that is the internet.
I think the most important thing is to analyze how resistant you are to internet distraction and negative influence and plan accordingly.
