A friend of mine is an excellent cook and has been for years. She can glance over a recipe that's she's never seen before and: see if it'd be a good recipe, see if it is a correct recipe that will work well, and tweak it so that it's better. Why can she do this? Because she loves to cook and does a lot of cooking.
Creative people can do the same, with whatever "follow your bliss" creative passion. Like my friend, the more we create, the better we get at creation. The more I write, the more I'm able to see if I've got a good recipe, see what's right and what needs to be tweaked.
As with any other skill, the more we practice, the better we become. I'm keeping that in mind as I work. And the 70 Days of Sweat helps keep me turning out pages! Who said: "You're not a writer until you've written a million words"?
How do you follow your bliss and keep following your bliss?
