If you aren't subscribing to Warren Ellis' newsletter, you should be even if you aren't a comics fan.
In the latest issue he drops a bit of wisdom that I think is of use to anyone creative:
Don't second guess yourself, just create.Someone on Tumblr asked me the following question:Once you've figured out that you're secretly always telling the same story, in one shape or another - how do you get around that? When you get tired of your own moves, however hermetically sealed they might look to a reader outside your head?And here's my answer:I’m sure any number of reviewers will tell you that in my case it’s not much of a secretYou’re spending too much time thinking about what other people might think and too much time second-guessing yourself. Go where your energy is, and when you come to a point where you need to make a story choice, go with the less comfortable one. It’s only time and paper. Ride the wrong way for a while and see what happens.
