Holly Lisle has an EXCELLENT web site, with a TON of information and encouragement for newbies and pros alike.
Here's an example: a post on courage.
Writing-World.com was one of my first and is still one of my favorite online writing resources.
Julia Cameron's books are a mainstay for me; I go back to them over and over when I need a boost.
I long ago gave up on paying for a Writer's Market subscription and went with the free Duotrope's Digest, which updates more often, is more reliable, and focuses on my genre. (While free, they really, really, do appreciate donations, though!)
Heather Sellers, author of Chapter After Chapter, has many a time kept me going when I was ready to give up.
Oriah Mountain Dreamer's What We Ache For is always close to hand these days.
