It will hardly be news that I think these two are creative. Still, I do recommend Wil Wheaton and Neil Gaiman and their blogs. They are both on Twitter.
Gaiman offers special advice for creative people, although it is good for everyone. Write a will. I suppose I should suggest, 'write to Wil' or something similar as I have connected them in this post.
Also, please keep in mind that GRRM is not your bitch.
Finally, beware of Wheaton's beard.
