I love this classic post from Hugh MacLeod. The mantra I always repeat to myself is "your blog is not about you." It's about what your readers are after. Hugh agrees in his own words:
"Nobody’s reading your blog because of your art. They’re reading your blog because THE PERSON YOU ARE inspires them...They’re reading your blog because the way you approach your work inspires them. It sets an example for them. It stands for something that resonates with them. IT LEADS THEM TO SOMEWHERE THAT THEY ALSO WANT TO GO."
